Re: Querying only for "+" character causes org.apache.lucene.queryParser.ParseException

[Kai Becker]

Hi,

you need to escape that char in search terms.
Special chars are + - ! ( ) { } [ ] ^ " ~ * ? : \ / at the moment.

The %2B is just the url encoding, but it will still be a + for Solr, so just 
put a \ in front of the chars I mentioned.

Cheers,
Kai

more results when adding more criterias

[Kai Becker]

Hi,
I have a field which has data like this:

 
   
Where  can have from 1 to 10 letters strings and  can have up 
to 4 digits.

It is defined like this:


  


  


When the user enters foo, i search for foo directly or something that starts 
with "foo ".
I don't want to find "fool" or "foop" or anything like this.
I also allow users to enter terms that they don't want to find.

So a query for  "foo NOT foo 123" is converted to this:

parsedquery_toString: "+(+(myField:foo myField:foo *) +(-myField:foo 123 
-myField:foo 123 * +*:*))",

My problem is that this finds more entries then just foo, which converts to 
this:
parsedquery_toString: "+(myField:foo myField:foo *)",

I have read a bit about the internal solr logic, using MUST, SHOULD and 
MUST_NOT, but still don't understand.

When I look at parsedquery_toString: "+(+(myField:foo myField:foo *) 
+(-myField:foo 123 -myField:foo 123 * +*:*))",
then I see two criteria A and B and both MUST be satisfied.
Criteria A is the same as parsedquery_toString: "+(myField:foo myField:foo *)", 
so the number of results MUST be identical here.
Since the final results must match both A and B, the number must be equal or 
lower than just A, right?

Where do I think wrong?

Thanks,
Kai
