About SmartSearch

To use SmartSearch, enter words and phrases separated by commas to find documents that contain any of the words or phrases specified. The more matched words in the document, the higher the result ranking. Variations of the word (plural form, suffixes added or removed, etc.) are also included in the search. 

Common Problems

If you are getting too many matches: 

• Try searching only in the titles of the documents by selecting the Search In Titles Only radio button on the search form.
• Try putting the word or phrase in double quotes. This will force the search engine to match the search text exactly as typed.
• Try adding more words to your search text, connecting them with AND.
• Select one or more checkboxes on the search page to constrain your search to only those topics of interest
• Reduce the number of checkboxes selected to only those topics of interest.
• If you're searching on the Industry-Wide Search Page , select one or more checkboxes reflecting only the sites that you would like to search.

If you are getting too few matches: 

• Try adding commas between words. If you typed a phrase (multiple words separated by spaces), SmartSearch will only present documents that contain the entire phrase.
• Try different words that might have the same or similar meaning.
• Try adding more words to your search text and connecting the words with commas.
• If you had selected the Search In Titles Only radio button, deselect it.
• If you were searching on the Xilinx Site Only Page, try our Industry-Wide Search Page

Using the Checkboxes

If you do not select any checkboxes the search assumes that all checkboxes are selected which means that your search is not focused to any source or topic. Once you select one or more checkboxes, the search will focus your search using only the selected checkboxes. 

Advanced Search Language

Boolean logic, wildcards, and zone searching allow you to compose refined queries : 

Boolean Logic

AND - Finds only pages which contain all search terms. 

Example: pci AND xc5000

• Effect: Narrows search results

OR - Finds pages which contain any one of the search terms. 

Example: pinout OR footprint

• Effect: Expands search results

ACCRUE (,) (smart OR) - Finds pages which contain either search term. Documents with both at the top of the results list. 

Example: CLB ACCRUE TBUF
Example: CLB, TBUF

• Effect: Expands search results. Like OR, but the more instances of words found, the higher the ranking of the document.

NOT (modifier)- Use with the AND operator to exclude terms from your search. 

Example: linkswitch AND <NOT> press release

• Effect: Narrows search results

Wildcards

Example: XC31* (find all XC3100 device family references)

• Effect: Expands search results by matching more words.

Example: XC3?42* (find only XC3042 and XC3142 references)

• Effect: Matches more strings, but limits wildcarding by character length.

Zone Searching

Example: pci <in> title

• Effect: Narrows search by only searching title. You can also focus your search to only check for matches in the title of a document by selecting the Search In Titles Only radio button on your search form.

• Effect: Narrows search by only searching the URLs of the document. This is useful if you know the filename you are searching for and want to set an agent on that particular document so you are notified if any changes are made to the specific document.
