[BUGFIX] Fix display of indexed search advanced search fields

There were some advanced search fields in indexed search that
disappeared after the last update.

In SearchController, method processExtendedSearchParameters, there were
some non-existing variables that were used in some conditions.
With this patch, those variables are initialized before the conditions
and all the advanced search fields in indexed search are shown again.

Releases: master, 8.7
Resolves: #84995
