[TYPO3] indexed_search results using subtitle

[Martin Bidner]

hello
(excuse my english first)

i?ve got mannnny pages named 0101, 0102, 0103,...1201,1202...
in subtitle these pages got "normal names" like "artikel about blabla.."

until yet there was no problem cause i used
tt_content.search.20.renderObj.10.field = pages_subtitle // pages_title
for searchresult, but now i want to upgrade to indexed_search_engine

is there an "easy" way to use pages-subtitle instad of title
in search results of indexed_search

(easy means i?m not very firm in php-coding)

thank you - have a nice evening

greet
martin

p.s.: i?m so amazed people can create things like typo3
(and that for free)
