Subject [jira] Commented: (NUTCH-573) Multiple Domains - Query Search
Date Wed, 14 Nov 2007 11:36:43 GMT

Doğacan Güney commented on NUTCH-573:
-------------------------------------

Why not fix NUTCH-479 and use it generally? If I understand correctly, after NUTCH-479 we
can support a query like "site:www.apache.org OR site:www.mozilla.org" , can't we? IMHO, all-uppercase
OR is more intuitive...

> 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"
