Span first queries

Elastic Stack Elasticsearch
1

Is there a way to perform a span_first query against a query_string or
match query? I'd like to use this in a rescore to improve relevance.

If I can't do that I'll have to do something silly like create another
field pre-chopped on the way into Elasticsearch.

The limitation of only able to use term queries comes from Lucene. I never
looked into why there is such a limitation in Lucene, but since they have a
lot of smart people working on the code, I assume there must be a good
reason. :slight_smile: Phrase queries do not have such a limitation.

I use span queries a lot where I require phrase queries with in order
terms. I pre-analyzed my queries by instantiating an AnalysisService
locally, which is only doable if using the Java API. Hackish, but it works.
Ultimately I need to move away from span queries.

Cheers,

Ivan
