Vikas Saurabh commented on OAK-4516:
------------------------------------
One of the possible solution could be to utilize
[WordDelimiterFilter.html#PRESERVE_ORIGINAL|https://lucene.apache.org/core/4_4_0/analyzers-common/org/apache/lucene/analysis/miscellaneous/WordDelimiterFilter.html#PRESERVE_ORIGINAL]
feature in default {{OakAnalyzer}}.
This has an obvious downside that it'd increase index size. So, we would
probably want to keep this configurable.

> It's sometimes useful to have original value being indexed to be stored as a
> term. One use-case could be like:
> * consider a couple of values to be indexed as {{abc_def}}, {{abcdef}}
> * On query, it seems reasonable to get both values for a query for {{abc*}}
> Currently, the values would get indexed like:
> * {{abc_def}} -> {{\[abc], \[def]}}
> * {{abcdef}} -> {{\[abcdef]}}
> So, the query {{abc*}} would only fetch {{abcdef}}
