Re: String field does not yield partial match result using qf parameter

[Jan Høydahl]

fieldType "string" is not tokenized, so your observation is correct. You need 
to use a fieldType with analysis and tokenization to get the behavior you want.

Re: String field does not yield partial match result using qf parameter

[Mugoma Joseph O.]

It looks like partial search works only with copied to field. This works:

$ curl
"http://localhost:8282/solr/links/select?q=text_ngrams:yengas&wt=json&indent=on&fl=id,domain,score";

String field does not yield partial match result using qf parameter

[Mugoma Joseph O.]

Hello,

I am newbie to solr.

I am trying out partial search (match). My experience is opposite of
http://lucene.472066.n3.nabble.com/string-field-does-not-yield-exact-match-result-using-qf-parameter-td4060096.html

When I add 'qf' to to dismax query I get no result unless there's a full
match.

I am using NGramFilterFactory as follows:

 
   
 
 
   
   
 
   
 

 ...


 

 ...

 

 ...

 


If I have yengas.com in indexed I can search for yengas.com but not
yengas. However, If I drop 'qf' I can search for yengas.


Example searches:

 $ curl
"http://localhost:8282/solr/links/select?q=domain:yengas&wt=json&indent=on&fl=id,domain,score";
 => "response":{"numFound":0,"start":0,"docs":[]


 $ curl
"http://localhost:8282/solr/links/select?q=domain:yengas.com&wt=json&indent=on&fl=id,domain,score";
 => "response":{"numFound":3,"start":0,"docs":[]

 $ curl
"http://localhost:8282/solr/links/select?defType=dismax&q=yengas&qf=domain^4&pf=domain&ps=0&fl=id,domain,score";
 => "response":{"numFound":0,"start":0,"docs":[]


 $ curl
"http://localhost:8282/solr/links/select?defType=dismax&q=yengas.com&pf=domain&ps=0&fl=id,domain,score";
 => "response":{"numFound":3,"start":0,"docs":[]


The partial match fails on dismax and normal query.

What could I be missing?


Thanks.

Mugoma.
