Hi,

I tried to isolate the problem, so I tested the following query on solr-4.6=
.0 :

http://localhost:8983/solr/collection1/select?q=3Dipod belkin&wt=3Dxml&debu=
gQuery=3Dtrue&q.op=3DAND&defType=3Dedismax&bf=3Dmap(query($qq),0,0,0,100.0)=
&qq=3D{!edismax}power

The error is :
org.apache.solr.search.SyntaxError: Infinite Recursion detected parsing que=
ry 'power'

And the stacktrace :

Is this a bug ?

Thank you,

Hi,

Thank you for your response.

When I try the URL you sent me, I get the following error message :

org.apache.solr.search.SyntaxError: Infinite Recursion detected parsing que=
ry 'beautiful Christmas tree'

Any idea what this means ?

Best regards,
Anca

Modified from Jan's solution. See his original post [1] to a similar discus=

Hi,

How to boost documents that contain all search terms in several of its fiel=
ds ?

Below you cand find a simplified example :

The query with Min should match:
q=3Dbeautiful Christmas tree&mm=3D2&qf=3Dtitle^12 description^2

There are two offers that match the query :
offer1 {title:"Christmas tree", description:"a joy for children"}

offer2 {title:"Christmas tree", description:"beautiful for holidays"}}

The first offer ranks before the second, despite of the fact that the secon=
d one contains all the search terms. I tried to play with the boosts of qf,=
 but the results vary a lot.

Is there a way to add a boost on all search fields, the same way we do with=
 pf on one field : pf=3Dtitle:2^3.0 ?

Thank you,
Anca
