About Finding Files in File Exchange Using Search to Find Files in File Exchange Finding Files by Product, Author, and Other Attributes in File Exchange |
Find files by using search words, searching for attributes, selecting tags, and sorting.
You can use all the methods at the same time.
It is more efficient to search first, and then refine the search results by selecting tags and changing the sort order.
Because the repository changes daily, criteria you use to find files now could show different results when you use the same criteria later.
Go to the list of files.
Type search words in the search field and press Enter.
File Exchange finds files in the repository whose titles, descriptions, or tags contain the search words you entered.
For an example, see Example — Finding and Downloading a File in File Exchange .
To view guidelines for entering search words:
Click the arrow in the search field.
From the menu, select Using the Search Field to Find Files.
View the relevant help topic.
You can search for files by their attributes, for example, files whose author is Jones. For more information, click the arrow in the search field and select Advanced Search Help.
In File Exchange:
Tags are keywords associated with a file.
Users create tags and apply tags to files.
Typically, a file has more than one tag applied to it.
There is no relationship among the tags applied to a file.
Use tags to:
Find files about a topic.
Label files that pertain to a topic.
Viewing Popular Tags for a List of Files. Popular tags are those tags users applied most often. Multiple users can apply a tag to a file. The popularity of a tag reflects the number of times the tag was applied by all users.
File Exchange shows popular tags above the list of files:
When the search field is empty, File Exchange shows popular tags for the entire repository.
After you select a tag or perform a search, File Exchange shows the popular tags associated with the resulting list of up to 50 files.
You can change the way that popular tags display:
To show or hide popular tags, click Tag View.
To see additional popular tags, make the File Exchange tool wider.
To change the view of tags, click Cloud or List:
Cloud view — The font size of a tag indicates its popularity.
List view — All tags have the same font size. You can see the popularity of a tag by the number in parentheses.
Viewing More Tags for a List of Files. When you want to see more than just the popular tags for a list of files, click More Tags. The resulting window:
Allows you to choose the view, as a cloud or a list
Shows the 250 most popular tags in the entire repository when the search field is empty
Shows all tags associated with the list of files when the search field is not empty
Does not show tags you already selected
Automatically closes when you click anywhere outside of it
Remains open if you click its top edge or drag the window by its top edge to another location
To See Different Tags. If you do not see tags of interest in popular tags or More Tags:
Change the search words, remove tags, or select different tags.
When the search field is not empty, and there are more than 50 results, you can change the sort order to see different tags.
Viewing Tags for a File. You can view tags for a file:
In the list of files, in the Tags column
On the file details page, in Everyone's Tags
For more information about Everyone's Tags and Your
Tags, click the information button
in Tags for
This File.
Selecting Tags to Find Files. You can select tags before or after entering search words. In general, it is more efficient to search first, and then refine the search results by selecting tags.
Select one or more tags from any of the following locations:
Popular tags shown above the list of files
The window that opens when you click More Tags
The Tags column in the list of files
Tags for This File on the file details page
After you select a tag:
The tag name appears below the search field. Example
of control tag selected:
![]()
tag:"tagname" appears in the search field.
File Exchange looks for files that have variations of the selected tag associated with them.
File Exchange reports the files that best match all your criteria.
For example, when you select the tag control, File Exchange finds files that have the tag controls design, pid controller, and other variations. The reverse is not true: if you select the tag pid controller, File Exchange does not find files with the tag control.
Removing Tags You Already Selected to Expand Results. When selecting a tag produces too few results, remove it to see more results. To remove a selected tag, do one of the following:
Click the close button
for the tag.
Delete tag:"tagname" from the search field.
Directly Entering a Tag Name. When you do not see a tag but want to use it to find files, you can directly enter the tag in the search field.
To enter the tag directly, type tag:"partial_tagname", and press Enter.
For example, if you do not see the tag control in popular tags or More Tags, enter tag:"control" in the search field.
For more information, click the arrow in the search field and select Advanced Search Help.
The example illustrates advanced aspects of using tags to find files.
Open File Exchange and view the tags as a list: for View tags as, select List. See Ways to View Tags.
You want to find files to help you compare your data, which has small sample sizes, to known distributions.
The statistics tag looks relevant. But it could be too general because it was applied 712 times.
You think a distribution tag could help, but do not see it.

Type tag:"distribution" in the search field, and press Enter. For more information, see Directly Entering a Tag Name.
File Exchange reports 64 files that have the distribution tag or a variation of it applied to them.
The statistics tag was applied 20 times among the 50 files listed. The tag could be applied additional times among the 14 matches not listed.

Narrow your results by selecting the statistics tag. For more information, see Selecting Tags to Find Files.
File Exchange reports 31 files that have both the distribution and statistics tags applied to them. The number of times the statistics tag was applied increased from 20 to 31. Before you selected the statistics tag, it was applied only 20 times among the 50 files listed, as described in step 2. But there were 64 results in step 2, so the statistics tag was also applied 11 times among the 14 results that were not listed then.

None of the popular tags are of interest. The FISHERTEST file is close to what you want. But the description shows it as being for a 2-by-2 contingency table and you have a 2-by-3 table.
Look for a fisher tag to see if there are other files for the Fisher test:
Select More Tags.
From the resulting window, select the fisher tag to add it to your criteria.
For more information, see Viewing More Tags for a List of Files.

File Exchange reports one file that uses all three specified tags. The file is not of interest.
Expand the results by removing a tag from your criteria. Remove the least relevant tag, distribution, by clicking the close button for it. For more information, see Removing Tags You Already Selected to Expand Results.

File Exchange reports six files with the tags statistics and fisher applied to them. The tags include fishers exact test 2x3 matrix, which is what you need. Select the tag.

One file has the three selected tags applied to it. The file is relevant to you, has a good rating, and was downloaded often. Download it by clicking the Download button.

When a tag is associated with a file, you can apply the tag to the file to identify it as relevant to you.
To apply a tag to a file, go to the details page for the file and use Everyone's Tags.
For more information, including an example, click the Tags
for This File information button
on the file details page.
You can add a new tag to a file. See Adding Tags to a File.
Clear the search field. The default list of files displays, using the sort order you last specified. For more information, see Viewing the Default List of Files.
When too few or too many files match your criteria, try the following suggestions to get better results.
| To Get More Matches | To Get Fewer Matches | Explanation |
|---|---|---|
| Remove tags. | Add tags. | Because results must have all the tags you chose, specifying fewer tags results in more matches. |
| Directly enter partial tag names instead of selecting tags. | Select tags or enter full tag names. | You can get more results when you type tag:"partial_tagname" in the search field than when you select a tag. For example, typing tag:"control" in the search field instead of selecting the tag design controller results in more matches. |
| Use search words instead of tags. | Use tags instead of search words. | You get more results by searching for a word than by selecting a tag of the same name. For example, typing control in the search field instead of selecting the tag control results in more matches. |
| Remove " " from around search words. | Add " " from around search words. | Without quotation marks, you find files that have all the search words, but not necessarily in sequence. |
| Try again in about 15 minutes. | N/A | When you add a new tag and use it to find files, File Exchange could report no files found. It could take up to 15 minutes after adding a new tag before you can use it. |
| Check the search field for mistakes. | You could have inadvertently removed a meaningful space or quotation mark. For guidelines, click the arrow in the search field and select Using the Search Field to Find Files | |
| Be sure that search attributes and values are valid. | For correct names and values, click the arrow in the search field and select Advanced Search Help. | |
| Start over by clearing the search field. | If you want to start over instead of changing criteria you already provided, clear the search field. | |
If you have too many results, try the opposite of the suggestions:
Add tags
Use full tag names
Use tags instead of search words
