Common Solr names

[pkiraly]

In a repository I found an interesting file, that maps MARC fields to Solr field with a set of pipeline:
https://github.com/uvalib/virgo4-marc-convert/blob/master/lib_solrmarc_install/solr7_index.properties

title_tsearch_stored = 245a, cleanEnd
title_tl = 245a?(ind2 > 0), cleanEnd, stripInd
title_ssort_stored = 245abnp, join(" : "), clean, titleSortLower, first
title_sub_tsearch_stored = 245bnp, cleanEnd
full_title_tsearchf_stored = 245abnp, cleanEnd
full_title_tl = 245abnp?(ind2 > 0), cleanEnd, stripInd

It would worth to check this domain specific language, and maybe reuse some of the names.
