About SmartSearch

SmartSearch is the best Programmable Logic search engine in the Industry.SmartSearch searches over 65 different sites rich with programmable logic content.

To use SmartSearch, enter words and phrases 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 are getting too few matches: 

• Try different words that might have the same or similar meaning.
• Try adding more words to your search text.
• If you had selected the Search In Titles Only radio button, deselect it.

You can focus your search using the checkboxes on the search forms. SmartSearch Sources limit your search to a specific web site or category of pages within a single web site. SmartSearch Topics allow you to select topics of interest, and the search will find all matches using related keywords to your selected topic. 

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. 

You can create your own advanced query using the language described below. 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
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

* - Matches any number of characters.
Example: XC31* (find all XC3100 device family references)
Effect: Expands search results by matching more words.

? - Matches one character
Example: XC3?42* (find only XC3042 and XC3142 references)
Effect: Matches more strings, but limits wildcarding by character length.

Zone Searching

Zone searching permits you to limit your search by only searching in the titles or URLs of documents.
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.

Example: url <contains> www.xilinx.com/bvdocs/publications/9572.pdf
Effect: Narrows search by only searching the URLs of the document.

The results of your search are sorted based on relevance. Documents which match your search criteria in the title, or in the keywords of the document, are filtered to the top of your search results.
