I am indexing and storing date time with minute resolution. I need to do
date range query and also do sorting on this field. I am having almost 30
million records spread across 20 database.
option1:
To index the date time as string
option2:
To index date, hour and minute separately as number.
As far as I have encountered the best and simplest option is to use date
time as string (mmddHHmmss or mmdd) as per your requirement.

If you are building queries manually, bypassing analysis, you just
need to make sure that you know what you are doing. As a trivial
example, if you are indexing with an analyzer that downcases
everything then you need to pass lowercase terms to TermQuery.
You can still use an analyzer where appro
Are you sure that you close the IndexWriter *before* you
open your _Searcher in your program (it kinda looks
like a test program is why I'm asking).
If the above is OK, I'd really recommend getting a copy
of Luke, writing your index to a FSDirectory and looking
at it with Luke.
Barring all that,
This question, along with many possible answers has been
discussed many times, so there's a wealth of information
in the searchable archive.
The short form is "it depends". Do you want to sort? In
that case storing a single field will cost you when sorting.
Store the coarsest granularity you can.
Does anyone have an example using this?
I have a SynonymEngine that returns a an array list of strings, some of
which may be multiple words. How can I incorporate this with my
SynonymEngine at index time?
Also, the javadoc for the ShingleMatrixFilter class says:

Eric,
Unit tests should help you see how this can be used:
./contrib/analyzers/src/java/org/apache/lucene/analysis/shingle/ShingleFilter.java
./contrib/analyzers/src/java/org/apache/lucene/analysis/shingle/ShingleAnalyzerWrapper.java
./contrib/analyzers/src/java/org/apache/lucene/analysis/shingle
The unit tests don't really show how I could use it for synonyms at
index time- does anyone have sample code? Is it possible?
