reduce jena-text MAX_N parameter to 100000 to speed up text queries. fixes #41
SPARQL performance optimization for queryConcepts: don't use language fallback when it is not necessary. Helps with #42 (though the alphabetical index is still slow)
reindent SPARQL query to take up less space, so a GET request (cacheable) is used instead of a POST. Fixes #42
get alphabet index letters with a SPARQL query instead of hardwiring them. Fixes #34
add separate, simpler (and faster) SPARQL query for performing lookups for the alphabetical index
code cleanup: no need for regex support in queryConcepts anymore, so removed dead code
rewrite and simplify alphabetical index SPARQL query. Much faster now. Fixes #42
use Unicode character properties instead of POSIX character classes to distinguish between letters, numbers and special characters for the alphabetical index
