Subject [jira] [Commented] (SOLR-1535) Pre-analyzed field type
Date Fri, 13 Apr 2012 10:22:13 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13253263#comment-13253263

Chris Male commented on SOLR-1535:
----------------------------------

Can't we just provide an abstraction so people can choose whatever format they want? You might
use JSON out-of-box, but Jan could implement an Avro alternative if he wanted too.  That also
gives us a way to grow the format as our needs change.

> PreAnalyzedFieldType provides a functionality to index (and optionally store) content
that was already processed and split into tokens using some external processing chain. This
implementation defines a serialization format for sending tokens with any currently supported
Attributes (eg. type, posIncr, payload, ...). This data is de-serialized into a regular TokenStream
that is returned in Field.tokenStreamValue() and thus added to the index as index terms, and
optionally a stored part that is returned in Field.stringValue() and is then added as a stored
value of the field.
> This field type is useful for integrating Solr with existing text-processing pipelines,
such as third-party NLP systems.
