Changing the relevance ranking of certain search words

If your database has a full text index, you can use the Termweight operator to change the relevance ranking of search words, thus increasing or decreasing their importance in the search. Documents in which the search text is most important appear at the top of the list of search results (when you sort the results by relevance).

To use the Termweight operator, type your search text as follows:

termweight 80 word1 or termweight 20 word2
where the numbers following "termweight" can be any integer from 0 - 100.

Examples of using the Termweight operator
The table below shows some examples of using the Termweight operator to change the relevance ranking of search words.
