1. Query word/phrase accepts English alphabets and dash only (i.e. A-Z, a-z, -), case-insensitive.
2. Search string syntax word^pos. [e.g. book^nn, book^vb ^dt, ^vb ^dt ^nn, etc.]
  • The symbol ^tag indicates the tag to be searched for. The string in front of the caret symbol ^ is the query word.
  • A maximum of 5 units of 'word', 'word^pos' or '^pos' can be used for query.
  • A caret with a number (e.g. ^2) in the middle of the search string instructs the search engine to skip two words in between any two query parameters (e.g. book ^2 advance).
  • Head and/or tail partial search of the query word/phrase is possible by adding '  -  ' to the front or end of the query word/phrase (e.g. -ment, advan-, -fine-)
  • Tail partial search for the POS tag is possible by adding '-' at the end of the POS tag (e.g. ^NN- will return ^NN, ^NNS, ^NNP, ^NNPS)
  • Units are separated by a space. Punctuation is not accepted.
