Get results ordered by field content starting with specific word

[darul <da...@gmail.com>]

I have seen many threads talking about it but not found any way on how to
resolve it.

In my schema 2 fields :



Results are sorted by field2 desc like in the following listing when looking
for "word1" as query pattern:



I would like to get Doc3 at the end because "word1" is not at the beginning
of the field content.

Have you any idea ? 

I have seen SpanNearQuery, tried FuzzySearch with no success etc...maybe
making a special QueryParserPlugin, but I am lost ;)

We use Solr 3.4

Thanks

Meaning I need to implement my own QueryParser ?

If re-index is not an option, then writing custom is necessary to use SpanFirstQuery. You need to add it as an optional clause (with high boost) your whole boolean query. 

Also you can try and vote SOLR-839. With it it may be possible to use SpanFirstQuery.

Well, at indexed time I can not touch because we do not have data to index
anymore.

To use SpanFirstQuery, I need to make a custom ParserQuery ?

May be you can make use of SpanFirstQuery.

http://lucene.apache.org/java/3_1_0/api/core/org/apache/lucene/search/spans/SpanFirstQuery.html

However, I would insert an artificial token (e.g. BEGIN_OF_DOC) before indexing my fields. And use a phrase query or something to boost documents starts with word1. e.g. "BEGIN_OF_DOC word1"
