How does Lucene decide which fields to index?
Hi,
I am using lucene 4.6.0 to index a dataset.
I have the following fields:
doctitle, docbody, docname, docid, date.
But when I access the fields using indexReader.getTermVectors(indexedDocID)
then I only get two fields
docbody and docname.
How do I index so that I also get doctitle?
Thank you.
Regards,
Sachin Kulkarni

You tell it what you want. See the javadocs for
org.apache.lucene.document.Field and friends such as TextField.

Thank you Ian and Kumaran.
I checked that when I am reading back from the IndexReader, the fields are
getting stored but not indexed.
Since I am using Lucene's Benchmark utility to index the data, I have to
trace the code to see how it is using the in-built TREC parser to index
data.
But somewhere I am missing the important link in the process.
>From what I see, field.store is specified on all the fields, but
field.index is not specified explicitly.
Thank you again, I will keep looking into the code.
Regards,
Sachin

You should know two things to get this.
1.Indexed fields can be searched.
2.Stored fields can be fetched.
Check your code whether you are storing all fields.
