I think you can just write a TokenFilter which sets the
PositionIncrementAttribute of every other token to 0. Then you can use
StandardTokenizer and wrap it with that filter.

Hi,
I'm looking a solution for the following format in solr/lucene 5.2.1
version:
Text eg: "fast wi fi network is down". If using
solr.StandardTokenizerFactory , I have the "Position " corresponding to

I can’t seem to detect any issues with the final custom analyzer declared in
this code snippet (The one that attempts to use a PatternMatchingTokenizer and
is initialized as sa), but it doesn’t seem to be hit when I run my indexing
code despite being in the map. It is indexed finally but I assu

(fastQuery) && (slowQuery)
Is there a way to tell Lucene to execute the fastQuery first so it can
potentially skip the slowQuery if there are no results from the fastQuery?
I don't think making the slow query a filter (Occur.
2. Is the "Index" saved as a file or loaded into the memory?
Adding to Modassar's comments:
Almost all "real" implementations save the index to disk and
read selected portions back in to memory as needed, otherwise
the data isn't permanent. In the Lucene world, I'd start with
NRTCachingDirectory.
Please see my comments in-line.
1. For the indexing of these chapters, how many fields that need to be
declared? Can I just declare only one field for the contents?
This depends on what you need to search with. E.g if only plain content
(chapters) are to be searched then one indexed field is requ
Good day
I am new to Lucene and have started to explore Lucene.
I have questions:
I have a book in which all the chapters are in pdf. I plan to index all
these individual chapters in Lucene using Tika for the text extraction.
