Hi, we are designing the search architecture for a corporate web application. We'll be using Lucene.net for this. The indexes will not be big (about 100,000 documents), but the search service must be always up and always be up to date. There will be new documents added to the index all the time and concurrent searches. Since we must hav...
How to use booleanQuery with StandardAnalyzer in Lucene Search? ...
Given that Lucene is a robust document based search engine could it be used as an Object Database for simple applications (E.G., CMS style applications) and if so what do you see the benefits and limitations? I understand the role of the RDBMS (and use them on a daily basis) but watned to explore other technologies/ideas. For example ...

Wondering how to achieve pagination in Lucene, as it does not inherently support pagination. I basically need to search for 'top 10 entries' (based on some parameter) then 'next 10 entries' and so on. And at the same time I don't want Lucene to hog memory. Any piece of advice would be appreciated. Thanks in advance. ...

I have some code using Lucene that leaves the default conjunction operator as OR, and I want to change it to AND. Some of the code just uses a plain QueryParser, and that's fine - I can just call setDefaultOperator on those instances. Unfortunately, in one place the code uses a MultiFieldQueryParser, and calls the static "parse" method...

Hi. I'm considering the use of Apache solr for indexing data in a new project. The data is made of different, independent types, which means there are for example botanicals animals cars computers to index. Should I be using different indexes for each of the types or does it make more sense to use only one index? How does using ...
Hello, I'm looking for feedback on which analyzer to use with an index that has documents from multiple languages. Currently I am using the simpleanalyzer, as it seems to handle the broadest amount of languages. Most of the documents to be indexed will be english, but there will be the occasional double-byte language indexed as well. A...

We plan to use lucene as FTI-service. Amongst other things, we want to build a tag-index, based on a tag-attribute of our documents that simply contains space-delimited tags. Now for suggesting tag-completions, it would be great if there was a way to access all unique keywords of a given index. Lucene must be able to do that internally...
I was using something like: Field notdirectory = new Field("notdirectory","1", Field.Store.NO, Field.Index.UN_TOKENIZED); and queries like "notdirectory:1" can be processed quite well all the time. But recently I've changed the "Field.Store.NO, Field.Index.UN_TOKENIZED" to index a non-numeric string: Field stateField = new Field("st...
