We used to have a search, that checks two columns for some words. Both columns must contain some words provided, so we use AND … no doubts FULLTEXT INDEX is used on the columns.
The select is more or less like this:
SELECT * FROM SomeTable WHERE (CONTAINS(Column1, 'word1 OR word2') AND CONTAINS(Column2, 'word3 OR word4'))
now we need to add ranking to the result. We would like to use CONTAINSTABLE functionality … for only one column its simple. Something like:
SELECT SomeTable.*, tmp.RANK FROM SomeTable INNER JOIN CONTAINSTABLE(SomeTable, Column1, 'word1 OR word2') as tmp ON tmp.[KEY] = SomeTable.ID
Is it possible to do it with 2 columns BUT consider that I only need to search for word1 or word2 in column1 (not interested if we have word1 or word2 in column2). Also consider AND that was in where clause. Is there something like:
SELECT SomeTable.*, tmp.RANK FROM SomeTable INNER JOIN CONTAINSTABLE(SomeTable, (Column1, Column2), 'column1:(word1 OR word2) AND column2:(word3 OR word4)') as tmp ON tmp.[KEY] = SomeTable.ID
You can do this with an inner join on a second containstable, although you might want to do something a bit fancier than adding the ranks together as I have in the sample
