Hi.

I’m using MLT. Trying to change percent\_terms\_to\_match parameter, but  
nothing changes.

Values 0.3, 0.5, 1

returns same results including only 1 term match between docs.

Is it correct?

Sample of my query:

/\_mlt?mlt\_fields=positive,negative&min\_doc\_freq=1&max\_query\_terms=1000&analyzer=whitespace&percent\_terms\_to\_match=0.5

It is impossible to say without knowing your data.

I suggest you play with min\_term\_freq, min\_doc\_freq - you're probably  
testing this on a small number of docs.

I can tell you that we're using mlt with great success in production

My data just set of md5 strings divided by space. This md5 hashes of my  
specific objects. There 30 to 500 different hashes (terms?) in one doc with  
total of 160 to 2500 tems (one hash may be repeated from 1 to 10 times)

I need to find docs, where more than only 1 or 2 terms (md5 hashes) is  
matches.
