Hello,

I want to implement the following filter for a certain field in my  
document.

If less than 65% of the words match, I want this document be filtered  
out. The order of words doesn't matter. For example:

field contains: "word1 word2 word3", query is "word1 word2" --\> a  
match, 66% (so not filtered out)  
field contains: "word1 word2 word3", query is "word2 word1" --\> a  
match, 66% (so not filtered out)  
field contains: "word1 word2 word3", query is "word1" --\> not a match,  
only 33% (so filtered out)  
field contains: "word1 word2", query is "word1" --\> not a match, only  
50% (so filtered out)  
field contains: "word1 word2", query is "word1 word2" --\> a match,  
100% (so not filtered out)

Does anybody has any suggestions on what analyzer I should use (id I  
need a special one) and/or what query I can use?

thanks,  
Bert Gossey
