Re: How to integrate nlp in solr
Aman, I feel focusing on "Question-Answering" and "Information Extraction" components of NLP should help you achieve what you are looking for. Go through this book *Taming Text * (http://www.manning.com/ingersoll/ ) . Most of your queries should be answered including details on implementation and sample source codes. To state naively : NLP tools gives you the power to extract or interpret knowledge from text, which you basically store in the lucene index in form of fields or store along with the terms using payloads. During query processing time, you similarly gather additional knowledge from the query (using techniques like query expansion, relevance feedback, or ontologies ) and simply map those knowledge with the knowledge gained from the text. Its an effort to move to semantic retrieval rather than simple term matching.

Re: Solr index searcher to lucene index searcher
Hi , Thanks Chris . For every document that matches the query i want to able to compute the following set of features for a query document pair LuceneScore ( The vector space score that lucene gives to each doc) LinkScore ( computed from nutch ) OpicScore ( computed from nutch) co-rd in title,content,anchor,url wt of Entity in title,content,anchor,url length of title,content,anchor,url sum-of-tf in title,content,anchor,url sum-of-norm-tf in title,content,anchor,url min-of-tf in title,content,anchor,url max-of-tf in title,content,anchor,url variance-of-tf in title,content,anchor,url sum-of-tf-idf in title,content,anchor,url site-reputation-score enity-support-score domain score url-click-count query-url-click-count num-of-slashes-in-url Based on these above features i want to build a machine learned model that will learn to rank/score the documents .i am trying to understand how to compute the features efficiently on the fly. Looking into the index and computing these features seems to be very slow . So for the time being i wanted to implement the same by looking into the TopK documents.Few of these features has to be computed on the fly and some of them are computed while indexing and stored in the index . I need to be able to look into all features to score/rank the final set of documents. Thanks , Pom..

Re: Solr index searcher to lucene index searcher
Hi , Thanks Chris. I had been using Nutch 1.1 . The Nutch IndexSearcher used to call the lucene IndexSearcher . As the documents are collected in TopDocs in Lucene , before that is passed back to Nutch , i used to look into the top K matching documents , consult some external repository and further score the Top K documents and reorder them in the TopDocs array . These reordered TopDocs is passed to Nutch . All these reordering code was implemented by Extending the lucene IndexSearcher class . The lucene core that comes with solr is a bit different from the one that used to come with Nutch 1.1 . As a result implementing the same is not straight forward .Moreover , i cannot figure out at which point exactly the SolrIndexSearcher makes a direct Interaction with LuceneIndexSearcher . With FunctionQuery i loose the flexibility of looking into the documents before passing to the final result set. Now i am using solr 3.4 and i would like to implement the same between solr and lucene. Thanks , Pom On Wed, Apr 24, 2013 at 3:05 AM, Chris Hostetter wrote: > > : > > .

Re: Solr index searcher to lucene index searcher
Hi , Timothy,Thanks for pointing out . But i have a specific requirement . For any query it passes through the search handler and solr finally directs it to lucene Index Searcher. As results are matched and collected as TopDocs in lucene i want to inspect the top K Docs , reorder them by some logic and pass the final TopDocs to solr which solr may send as a response . I need to know the point where actually these interaction between solr and lucene takes place . Can anyone please help where to look into for this purpose . Thanks..

Solr index searcher to lucene index searcher
Hi , Can anyone please point out from where a solr search originates and how it passes to the lucene index searcher and back to solr . I actually what to know which class in solr directly calls the lucene Index Searcher . Thanks. Pom
how to skip test while building
Hi All, I am new to Solr . I am using solr 3.4 . I want to build without building lucene tests files in lucene and skip the tests to be fired . Can anyone please help where to make the necessary changes . Thanks, Pom
