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

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

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:
fieldType name=text_edgengrams class=solr.TextField
analyzer type=index
tokenizer class=solr.LowerCaseTokenizerFactory/
filter class=solr.NGramFilterFactory minGramSize=3
maxGramSize=15/
/analyzer
analyzer type=query
tokenizer class=solr.LowerCaseTokenizerFactory/
/analyzer
/fieldType
...
field name=text_ngrams type=text_edgengrams indexed=true
stored=false multiValued=true /
...
field name=domain type=string indexed=true stored=true/
...
copyField source=domain dest=text_ngrams/
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:yengaswt=jsonindent=onfl=id,domain,score;
= response:{numFound:0,start:0,docs:[]
$ curl
http://localhost:8282/solr/links/select?q=domain:yengas.comwt=jsonindent=onfl=id,domain,score;
= response:{numFound:3,start:0,docs:[]
$ curl

$ curl
http://localhost:8282/solr/links/select?defType=dismaxq=yengas.compf=domainps=0fl=id,domain,score;
= response:{numFound:3,start:0,docs:[]
The partial match fails on dismax and normal query.
What could I be missing?
Thanks.
