# directory with txt files

LOWER=krankenkassen
UPPER=Krankenkassen

mkdir ${INPUT}

# store one lowercase word
echo ${LOWER} > ${INPUT}/lower.txt

# who am i
omindex --version
quest --version

# clean up database 8)
rm -rf testdb

# create omega index, url doesn't matter
omindex --verbose --db=testdb --url=/bla ${INPUT}

# query database for word in Upper and lower case
quest --db=testdb ${UPPER} | tee test-nostem.out
quest --db=testdb ${LOWER} | tee -a test-nostem.out

# should have been fine.


# now ... clean up the database 8)
rm -rf testdb

# create omega index, use german stemmer
omindex --verbose --db=testdb --url=/bla --stemmer=german ${INPUT}


# try again and query database for word in Upper and lower case
quest --db=testdb ${UPPER} | tee test-stem.out
quest --db=testdb ${LOWER} | tee -a test-stem.out

# the 'lower case' one should fail. which is weird.

diff test-nostem.out test-stem.out
