OR query strange results

[Danilo Tomasoni]

Hello all,




and this odd situation happened


- A. query with N alternatives returns ~130.000 documents

- B. query with N-3 alternatives returns ~ 6.000.000 documents


N is relatively small in this case, but in general can be large.




The query is fully positive (no - or NOT inside).


Query A/B are attached.

I also tried with debug=all and I noticed










Thank you

Danilo

I'm performing some queries with a big list of terms in OR on our solr instance, How it's possible that if I specify less terms to match the number of results get higher? "parsedquery": "+(DisjunctionMaxQuery((abstract_methods:tuberculosi | ... ) DisjunctionMaxQuery( | .. | .. ) just on the first sub-parenthesis of the query. why is that? is this the reason of the change in number of results? if yes, how can I create a pure-or query (everything optional?) If you are wondering why I'm adding sub-parenthesis, that's to avoid the max boolean clauses error (If you know some other method that allows phrase searches please tell me)
