Uniform search through all subcorpora is misleading

[Promme Bosken]

This is a point which should be explained in the FAQ text document which I proposed earlier. We suggest uniformity by offering a search interface covering Frisian from 1200-2000, but the search results must be interpreted differently depending on whether the results come from 1800-2000 (no lemmatisation, no variant spellings of search word found) or from 1600-1800 (lemmatisation, all spellings found). Furthermore, Old Frisian offers problems of interpretation and various manuscripts, unique to Old Frisian. Most researchers will be interested in one of these three subcorpora, and they must know the limitations of searches. This can be explained in a text document for users.
