Spellcheck

This will tell the algorithm to keep words, even if the spellchecker did not find a close, matching word that is potentially correct. By default, words without a close correct match are excluded as they are possibly names of places and people while words that are very close to a suggested word are likely misspelled. If you check this, expect to see more words in your results.

This parameter changes how many words are identified as incorrect, using a larger vocabulary which consists of common words and titles of Wikipedia articles. It also adds several heuristics to filter out incorrect words. For most applications, "Medium" will provide a good balance between true positives and false positives while "Low" is appropriate in cases with too many words reported. On the other hand, "High" is mostly equivalent to using hunspell by itself without additional dictionaries or heuristics and thus is highly discouraged as it often reports hundreds of words that are not in the canonical dictionary ("High" generates similar results as using the OpenOffice spellchecker).

Some of the heuristics employed are filtering out words that are common, filtering out words that appear as a title of any Wikipedia article (names and places mostly), filtering out words that appear multiple times in an article, filtering out words that are likely not in the target language and filtering out composite words (mostly for German).

Which text to check. By default, the algorithm does not check within templates, weblinks, tables, lists, bold, italic text, quotation marks, at the end of the article etc. as these often contain names of places and people. If you choose to skip only Wiki Syntax, more text will be included (e.g. text in quotation marks, text at the end of the article). In relaxed mode
