Cleanup
Add fuzzy phrase query
Refactor phrase processing
Change RangeQuery syntax from [low - high] to [low TO high]

- a word can include the character '-'
  -> no conflict with date notations
Implement (inefficient) RangeQuery

- the processor functions additionally need the schema now
- do not test this with huge ranges - mind the autocompletion
Minor refactoring and cleanup; Change text bounds
Remove 'Pos' suffix of functions in Holumbus.Common.Positions
