Search Tips


Our new search engine is highly customizable, and we continue to make adjustments to it based on user feedback and our own testing. We appreciate hearing from you about your experiences with searching, especially specific examples, if possible.

Using the Search box

The search will look for information and resources on the CATIE websites ( and that contain all or some of the search terms – or keywords – that you enter into the Search box (for example, women transmission fact sheet).

You can also give the search additional instructions on how to look for your keywords by combining them in different ways:

  • Use AND to search for all your keywords in any order

for example, women AND transmission AND fact AND sheet

You don’t need to add the AND if you’re only using two keywords because they will automatically be searched as if they’re connected by AND.

  • Use quotes (“ ”) to search for all your keywords in a specific order like a phrase

for example, “safer sex

You can also start your search by browsing by subject if you can’t find the right keywords to search with.

Please note that you can use the search box to search and, but not the CATIE Ordering Centre.

Using the filters

After you’ve done a search, you can use the filter words in the Filter by boxes at the right of the search results screen to narrow your search results list.

Adding filters

Click on a filter word to shorten your results list to only the results related to that word (for example, clicking Guidelines and manuals (10) under Filter by Resource Category would shorten your results list to the 10 results that are a guideline or manual).

If you add a filter, a Current filters list will appear under the number of search results to show you the filters you’ve added. You can add more than one filter at a time.

Clicking on a filter may also reveal more specific filters that you can use to further narrow your results (for example, clicking on Treatment could potentially reveal other filters related to Treatment, such as HIV drugs).

Removing filters

In the Filter by boxes, click on the (remove) link next to a filter you’ve added to remove that filter and lengthen your search results list.

If you’ve added a filter as well as one of the more specific filters that appeared underneath it (for example, Treatment, and then HIV drugs), removing the broader filter will automatically remove the more specific filter as well (for example, removing Treatment will also remove HIV drugs).

Keep current filters

If you’ve added filters, you can check the Keep current filters box under the Search box to continue using the filters from your current search with your next new keyword search (for example, if you’ve added the filters Men who have sex with men and Research summary to your current search and you click the Keep current filters box before doing your next keyword search, the new search will only look within the resources that have been tagged by CATIE as being research summaries relating to men who have sex with men).

Language filter

Click the Show English results only button below the number of search results to see only the resources that are available in English. Resources that are not available in English will be removed from the results list. A Show results in all languages button will also appear. You can click this button to remove the language filter and bring the resources that are not available in English back to the list.

Using the sort options

The results list is sorted by best match, which means the most relevant results will appear first and the least relevant results will appear last.

You can also sort by publication date using the Date link in the Sort by box at the top of the page to switch between:

  1. ▼Date, which sorts results from newest to oldest (reverse chronological or descending order).
  2. Date, which sorts results from oldest to newest (chronological or ascending order).

To sort by relevancy again, click the Best match link.
