Filter Page Help

In the main panel of the interface you have various options for filtering the concordance you created with your query.

You have the following choices:

• To make sure your filter query appears in a concordance line, select positive. To make sure it doesn't, select negative.
• selected token: if your original query matched several words then you can determine which token (first or last) is used when calculating distance using the Search Span (below)
• Search Span boxes: Choose how many tokens in front or behind your node word (the KWIC i.e. the text that matched your original query) the match for the query you are filtering with can be; you can also exclude or include KWIC itself in the search span
• Query: the constraint (e.g. word or phrase) you are using for the filter. This field may have a different heading e.g. lemma depending on whether you selected a different "query type" in the expert options (see below).
• Query type: This is visible if you select Query Type in the expert options on the left hand side. With this, you can refine the type of query you wish to make from the following options
  • Simple: standard query uses exact words entered but will include capitalisation variants
  • Lemma: enter the stemmed form e.g. hat, and inflected forms of the same word will be included e.g. hats. You can specify the PoS (part of speech)
  • Word form: the exact word. This will include capitalisation variants but you can specify match case and you can specify PoS.
  • Phrase: uses the exact words entered e.g. hats and scarves
  • Character: you can supply a character string that can be matched e.g. ble will match words containing this character sequence. This might be particularly useful in languages where tokenisation is difficult.
  • CQL: uses complex query language see The Corpus Query Language (CQL)
