Erik Faessler updated UIMA-3096:
--------------------------------
Attachment: lucasToSolr.patch
This patch is a working realization of the issue's description. It adds some
new dependencies to the project, viz. solrj 4.3.1, commons-lang3 and gson 2.1.
There are currently no tests or documentation but could be delivered within the
specified time constraints for the issue.
Opinions? Is it a good idea to place the class(es) directly into LuCas? Could
users get confused about whether to use this AE or rather the existing SolrCAS
AddOn? I just wrote this for my own work and would be glad to share it, if
desired.
> A LuCas extension that allows ro index the Lucene documents created by LuCas

> Add a UIMA component extending LuceneDocumentAE that converts the Lucene
> document instances created by LuCas into Solr's PreAnalyzed field format
> (http://wiki.apache.org/solr/PreAnalyzedField). The converted documents are
> then sent in batches to Solr using the SolrJ API.
> On the Solr side, PreAnalyzedUpdateProcessorFactory
> (http://lucene.apache.org/solr/4_3_1/solr-core/org/apache/solr/update/processor/FieldMutatingUpdateProcessorFactory.html)
> can be used to restrict the pre-analyzed field values to an existing Solr
> schema. In case that the LuCas mapping file matches the Solr schema, it is
> easy as this:
> In solrconfig.xml, add this updateRequestProcessorChain:
> <updateRequestProcessorChain name="pre-analyzed-json">
> <processor class="solr.PreAnalyzedUpdateProcessorFactory">
> <str name="fieldRegex">.*</str>
> <str name="parser">json</str>
> </processor>
> <processor class="solr.RunUpdateProcessorFactory" />
> </updateRequestProcessorChain>
> Then, add this chain to the default update handler:
> <requestHandler name="/update" class="solr.UpdateRequestHandler">
> <lst name="defaults">
> <str name="update.chain">pre-analyzed-json</str>
> </lst>
> </requestHandler>
