Srikarthik Venkataraman commented on NUTCH-573:
-----------------------------------------------
I am very interested in using the Multiterm Query feature for searching in
multiple domains.
Can you please let me know if this patch is tested and available on any of your
release builds.
Can we expect this fix to be available in version 1.1 or could you provide us
intermediate release.
> Multiple Domains - Query Search
> -------------------------------
>
> Key: NUTCH-573
> URL: https://issues.apache.org/jira/browse/NUTCH-573
> Project: Nutch
> Issue Type: Improvement
> Components: searcher
> Affects Versions: 0.9.0
> Environment: All
> Reporter: Rajasekar Karthik
> Assignee: Enis Soztutar
> Fix For: 1.1

> Searching multiple domains can be done on Lucene - nut not that efficiently
> on nutch.
> Query:
> +content:"abc" +(site"www.aaa.com" site:"www.bbb.com")
> works on lucene but the same concept does not work on nutch.
> In Lucene, it works with
> org.apache.lucene.analysis.KeywordAnalyzer
> org.apache.lucene.analysis.standard.StandardAnalyzer
> but NOT on
> org.apache.lucene.analysis.SimpleAnalyzer
> Is Nutch analyzer based on SimpleAnalyzer? In this case, is there a
> workaround to make this work? Is there an option to change what analyzer
> nutch is using?
> Just FYI, another solution (inefficient I believe) which seems to be working
> on nutch
> <query> -site:"ccc.com" -site:"ddd.com"
