need help on OpenNLP with Solr

[rashi gandhi]

Hi,



I have applied OpenNLP (LUCENE 2899.patch) patch to SOLR-4.5.1 for nlp
searching and it is working fine.

Also I have designed an analyzer for this:

<fieldType name="nlp_type" class="solr.TextField"
positionIncrementGap="100">

  <analyzer type="index">

        <tokenizer class="solr.OpenNLPTokenizerFactory"
sentenceModel="opennlp/en-test-sent.bin"
   tokenizerModel="opennlp/en-test-tokenizer.bin"/>

                                <filter class="solr.StopFilterFactory"
ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true"/>

                                <filter class="solr.OpenNLPFilterFactory"
posTaggerModel="opennlp/en-pos-maxent.bin"/>

                                <filter class="solr.OpenNLPFilterFactory"
nerTaggerModels="opennlp/en-ner-person.bin"/>

                                <filter class="solr.OpenNLPFilterFactory"
nerTaggerModels="opennlp/en-ner-location.bin"/>

                                <filter
class="solr.LowerCaseFilterFactory"/>

                                <filter
class="solr.SnowballPorterFilterFactory"/>

   </analyzer>

   <analyzer type="query">

        <tokenizer class="solr.OpenNLPTokenizerFactory"
sentenceModel="opennlp/en-test-sent.bin" tokenizerModel
="opennlp/en-test-tokenizer.bin"/>

                                <filter class="solr.StopFilterFactory"
ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true"/>

                                <filter class="solr.OpenNLPFilterFactory"
posTaggerModel="opennlp/en-pos-maxent.bin"/>

                                <filter class="solr.OpenNLPFilterFactory"
nerTaggerModels="opennlp/en-ner-person.bin"/>

                                <filter class="solr.OpenNLPFilterFactory"
nerTaggerModels="opennlp/en-ner-location.bin"/>

                                <filter
class="solr.LowerCaseFilterFactory"/>

                                <filter
class="solr.SnowballPorterFilterFactory"/>

   </analyzer>

</fieldType>


I am able to find that posTaggerModel is performing tagging in the phrases
and add the payloads. ( but iam not able to analyze it)

My Question is:
Can i search a phrase giving high boost to NOUN then VERB ?
For example: if iam searching "sitting on blanket" , so i want to give high
boost to NOUN term first then VERB, that are tagged by OpenNLP.
How can i use payloads for boosting?
What are the changes required in schema.xml?

Please provide me some pointers to move ahead

Thanks in advance
