Before the recent OpenGrok re-indexing, it was possible to use a wild card "*" at the beginning of a search string. Now, it is no longer possible.

Test steps:
1. Open following link (searching for merk on the core repository): https://opengrok.libreoffice.org/search?project=core&q=*merk*&defs=&refs=&path=&hist=&type=

Expected results:
1. Search results are returned. (As was the case earlier.)

Actual results:
1. "Error message from parser:
Cannot parse '*merk*': '*' or '?' not allowed as first character in WildcardQuery"

Note: According to OpenGrok help under https://opengrok.libreoffice.org/help.jsp , the use of wildcards at beginning of a search string can be enabled using indexer option -a. I guess that the enabling was missed on the recent OpenGrok update.

Thanks in advance!
