Search Query with Lucene Query issue

Search Query with Lucene Query Syntax

If there are more than 4 OR or AND conditions, it does not work properly.

query : "ten" OR "teen" OR "alask"

query : "ten" OR "teen" OR "alask" OR "hihi" OR "bye"

This looks like a bug which I was able to reproduce. I opened an issue


The logic looks to be that there's an (undocumented) setting that 49% of the ORed terms must be matched. I don't think there's currently a way for you to relax this setting in your requests,


thx, @Mark_Harwood

Is it impossible to adjust later?

The code is unfamiliar to me but looks to allow an override for all search requests. I don't know how sysadmins get to change this though so I'll leave it to a member of the app-search team to respond.

thank you, @Mark_Harwood

When we input event words, we convert them into multiple words and then weave them with OR, so there are many cases where more than four are combined.

You could try using brackets to ensure there’s only max 2 clauses in between each bracket pair eg
( A or ( B or ( C or D) ) )

Not tried it and it’s ugly but it might work.
