+KorAP Lucene Index
+==================
+
+KorAP is available at
+https://korap.ids-mannheim.de/
+
+Limitations
+-----------
+
+### Tokenization
+
+The Lucene backend is not character but token based.
+In addition to that it only has support for one single tokenization.
+Although it supports multiple annotations on tokenizations, these
+annotations have to match the basic token's character offsets.
+
+Token annotations that do not match the basic tokenization are
+not indexed. Span annotations, that span a smaller range than one
+basic token, will not be indexed as well.
+
+Tokens are only indexed in case they are word tokens, i.e. not
+punctuations. This limitation is necessary to make distance query
+work on word levels.
+
+### Repetitions
+
+The maximum value for repetitions is 100.
+
+### Distances
+
+The maximum value for distance units is 100.
