Re: Search with the start of field

Thanks all,

I think SpapnFirstQuery will solve my problem. But does Solr 4.8 supports
xmlparser to use it? and does SpanFirst supports phrase search instead of
single term?

Thanks,
Mahmoud

Yes, definately SpanFirstQuery! But i didn't know you can invoke it via 
XMLQueryParser, thank Mikhail for that!

There is a tiny drawback to SpanFirst, there is no gradient boosting depending 
on distance from the beginning.

Re: Search with the start of field

2016-09-21 Thread Jan Høydahl 
You could do a hack with the field type similar to this text_lower_exact type: 
https://github.com/cominvent/exactmatch/blob/master/conf/schema.xml 

But if you only do the hack on the “index” side of analysis, you are free to do 
phrase searches like “ǣ DEF” which would only match the beginning since you 
include the very first token in the phrase.

It is not a perfect solution, and I’d like a native query operator to handle 
it, but so far we have not got one.
You may also try regex query, like myfield:/^DEF/

You can experiment with {!xmlparser}.. see

Search with the start of field

2016-09-21 Thread Mahmoud Almokadem 
Hello,

What is the best way to search with the start token of field?

For example: the field contains these values 

Document1: ABC  DEF GHI
Document2: DEF GHI JKL

when I search with DEF, I want to get Document2 only. Is that possible?

Thanks,
Mahmoud
