Problem while extending TokenizerFactory in Solr 4.4.0
Hi All,
I’m using Solr 4.4.0 distro and now, I have a strange issue while
extending TokenizerFactory with a custom class.
This is an excerpt of pom I use:
4.4.0
org.apache.lucene
*lucene*-core
${solr.version}
org.apache.lucene
*lucene*-analyzers-common
${solr.version}
org.apache.lucene
*lucene*-*queryparser*
${solr.version}
org.apache.solr
*solr*-core
${solr.version}
I always get the exception below during solr engine initialization:

Re: Problem while extending TokenizerFactory in Solr 4.4.0
I recompiled my classes with a public constructor and everything goes well. 2014-09-10 22:00 GMT+02:00 Erick Erickson : > Francesco: > > What was the fix?

Query parsing issue
Hi, I’ve written my own analyzer to index and query a set of documents. At indexing time everything goes well but now I have a problem in query phase. I need to pass the whole query string to my analyzer before the edismax query parser begins its tasks. In other words I have to preprocess the raw query string. The phrase querying does not fit my needs because I don’t have to match the entire set of terms/tokens. How can I achieve this? Thank you in advance. Francesco
R: Query parsing issue
Thank you very much, I've tried both the way that you have suggested to me. Then I've choosen to re-write the parse method by extending ExtendedDismaxQParser class. Francesco. -Messaggio originale- Da: Tomás Fernández Löbbe [mailto:tomasflo...@gmail.com] Inviato: mercoledì 6 marzo 2013 19:39 A: solr-user@lucene.apache.org Oggetto: Re: Query parsing issue It should be easy to extend ExtendedDismaxQParser and do your pre-processing in the parse() method before calling edismax's parse. Or maybe you could change the way EDismax is splitting the input query into clauses by extending the "splitIntoClauses" method?
