How to formulate query
Hi,
I am trying to make a solr search query to get result as under I am unable
to get do
I have a search term say "pit"
The result should have (in that order)
All docs that have "pit" as first WORD in search field (pit\ *)+
All docs that have first WORD that starts with "pit" (pit*\ *)+
All docs that have "pit" as WORD anywhere in search field (except first)
(*\ pit\ *)+
All docs that have a WORD starting with "pit" anywhere in search field
(except first) (*\ pit*\ *)+
All docs that have "pit" as string anywhere in the search field except cases
covered above (*pit*)
Example :
Pit the pat
Pit digger
Pitch ball
Pitcher man
Dig a pit with shovel
Why do you want to dig a pit with shovel
Cricket pitch is 22 yards
What is pithy, I don't know
Per capita income
Epitome of blah blah
How can I achieve this ?
Regards,
Prasanna.

Hi Prassana, This is a highly custom relevancy/ordering requirement and one possible way you can try is by creating multiple fields and coming up with query for each of the searches and boost them accordingly.
Thnx

Nothing exists currently that would do this. I would urge you to revisit the
requirements, this kind of super-specific ordering is often not worth the
effort to try to enforce, how does the _user_ benefit here?
Best,
Erick

Hello,
Even number of word can be used as scoring factor, but just for beginning.
You can cut the first word into separate field with _field mutating update
processor_ see
http://lucene.apache.org/solr/5_3_1/solr-core/org/apache/solr/update/processor/FieldMutatingUpdateProcessorFactory.html
then you can use query syntax to specify field:, boost^10 and wildcard*.
All such clauses might be combited with spaces as optional ones.
