Re: solr limits

In theory, yes. A single core/index is limited by the Lucene limit of 2.14 billion documents (document number is non-negative and represented as a signed Java "int"), but you can use shards to get a multiple of that. You can put 50 to 250 million (maybe more, depending on the data) documents in

Re: how to reduce the result size to 2-3 lines and expand based on user interest

The commonly used term is "snippet" or "snippet highlighting." Read: http://wiki.apache.org/solr/HighlightingParameters Try that approach. To expand, execute a fresh query for the specific document but with highlighting disabled or with highlighted parameters that provide a larger snippet siz

Re: Difference between textfield and strfield

A text field is a sequence of terms that has been tokenized while a string field is a single term (although it can also be multivalued.) Punctuation and spacing is ignored for text fields. Text tends to be lowercased, stemmed, and even stop words removed. You tend to search text using a handfu

Well the I do not have phrases for synonym expansion. So it does work well. The synonym expansion is done at query time.

Re: Difference between textfield and strfield

I should have said that you need to have both a text and string copy of the field. Make sure one of them is "stored" and do a copyField to the other field. Then your main query can be against the text field and the sort function query against the string field. -- Jack Krupansky -Original

1. Please be specific as to what is not working. Is a highlighting section returned in the results? Is the field missing? Or what? 2. hl.fragsize is in characters. Something like 300 is more realistic. 3. Your "f.DESCRIPTION.hl.snippets=5" is missing its XML tags. I don't think you need this any

Re: How to show Synopsis for textual description field

This is called "Document Summarization" and there is a lot of literature on the topic. None of it is implemented for Solr. All of them require some preprocessing so the summaries need to be stored during indexing. There is some natural-language processing and some math processing in most summarizer
