Ah, ok, so i cannot use PostingsHighlighter as it requires stored fields, right?
The field can be stored anywhere, not necessarily in the index. Here is
something that might work:
1. Store the N first characters of your field in a database.
2. Override PostingsHighlighter#loadFieldValues to load the field from
the database.
3. Specify your prefix length in PostingHighlighter's constructor.
However, it searches for a snippet only in the beginning of the document.
Hope this help,
Alexandre

Stored fields do not support Readers at the moment.

Subject: Indexing and storing very large documents
Hi there
I am searching for a way to store very large documents in a Lucene 4.7 index
and keep them ready to use the PostingsHighlighter for search result
highlighting.
I do not want to read the whole document into memory, as this would
consume too much memory or could cause an OutOHeapSpace. So i have to
use a Reader. Unfortunately i cannot pass a Reader to a Field with
FieldType.stored() = true. Any ideas? Code examples would be very cool :-)
Thanks in advance
Mirko
