Note: There is a special page for [SORT BY]

GROUP BY

WORD (default): Entries are not separated by part of speech (e.g. there is only one entry for clean, combining its use as an adjective and a verb).
LEMMA: All results are grouped by lemma (e.g. groups together swim, swimming, swam, etc). Useful when comparing results in two sections, where the specific conjugation of a verb (for example) doesn't matter.
NONE: This will show separate entries when a word has two or more part of speech tags (e.g. clean = [vvi], [j], etc). Usually you would not use this setting, but you do need to if you want the Keyword in Context entries to be limited to a particular part of speech.
BOTH WORDS / BOTH LEMMA: This is the best option for COLLOCATES searches where both the WORD(S) and COLLOCATES fields have several possibilities. For example, if you are looking for synonyms of flower near synonyms of pretty, then it will list all of the pairs: pretty flower, beautiful roses, etc. Otherwise, it would list only the COLLOCATE (pretty, beautiful, etc).

DISPLAY

RAW FREQ (default): The number of tokens in each section of the corpus
PER/MIL: Tokens per million words; allows better comparison across sections of different sizes.
RAW FREQ+: Raw frequency + per million
PER/MIL+: Per million + raw frequency
In any case, the coloring of the cells in the results table is a function of the normalized frequency (tokens per million words).

SAVE LISTS

NO (default)
YES: This allows you to save entries from a results set into a customized, user-defined list, which you can then retrieve later on and use as part of subsequent queries. For example, you could search for synonyms of beautiful, select certain entries, add more forms that you feel are missing, and then save this as your own [beautiful] list. (More information ...)

# HITS

Number of "hits" to see in the results set.
Default = 100
