--------------------------------------
Hi,
I designed an analyzer using OpenNLP filters and indexed some data on it.
<fieldType name="text_opennlp_nvf" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.OpenNLPTokenizerFactory"
sentenceModel="opennlp/en-sent.bin" tokenizerModel="opennlp/en-token.bin"/>
<filter class="solr.OpenNLPFilterFactory"
posTaggerModel="opennlp/en-pos-maxent.bin"/>
<filter class="solr.FilterPayloadsFilterFactory"
payloadList="NN,NNS,NNP,NNPS,VB,VBD,VBG,VBN,VBP,VBZ,FW" keepPayloads="true"/>
<filter class="solr.StripPayloadsFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true" />
</analyzer>
</fieldType>
<field name="Detail_Nvf" type="text_opennlp_nvf" indexed="true" stored="true"
omitNorms="true" omitPositions="true"/>
My problem is:While searching, SOLR sometimes return result and sometimes not (
but documents are there).
for example: if i search for Detail_Nvf:brett ,it returns a document
and after sometime again if i fire the same query, it returns Zero document
Iam not getting why SOLR results are unstable.
Please help me on this.
Thanks in Advance

> Now that OpenNLP is an ASF project and has a nice license, it would be nice
> to have a submodule (under analysis) that exposed capabilities for it. Drew
> Farris, Tom Morton and I have code that does:
> * Sentence Detection as a Tokenizer (could also be a TokenFilter, although it
> would have to change slightly to buffer tokens)
> * NamedEntity recognition as a TokenFilter
> We are also planning a Tokenizer/TokenFilter that can put parts of speech as
> either payloads (PartOfSpeechAttribute?) on a token or at the same position.
> I'd propose it go under:
> modules/analysis/opennlp
