Finally tsearch works ... somehow... remain a few questions
For now i am almost statisfied with my tsearch2 installation war over night
somehow it seems to work, finally...
3 probably easy questions remain...
1.) Is it possible to index already filled tables?
2.)Can i have seperated indexes for different columns in a table
3.) Can i create an extra Table just for my indexes that is not included
in my data table?
Greetings
Marcel

sure. It's written many times. Check to_tsvector() function
2.)Can i have seperated indexes for different columns in a table
why not, you may have separate indices or one index with different
weights assigned to each column (up tp 4 columns)
3.) Can i create an extra Table just for my indexes that is not included
in my data table?
I don't understand this. Example, please.
Seems, you need to reread documentation.

Most important - index consistency and native access to document metadata.
