Search on document title

Two search modes are available:

  1. 'at least one word' mode
    The search returns all the documents whose title contains at least one of the word specified in the search string. The search is case-insensitive.
  2. 'all words' mode
    The search returns all the documents whose title contains all the word specified in the search string. The search is case-insensitive.

Search on document content

Three search modes are available:

  1. Integral mode
    This is a natural language search, that interprets the search string as a phrase in natural human language (a phrase in free text). There are no special operators. The stopword list applies. In addition, words that are present in more than 50% of the rows are considered common and do not match. Full-text searches are natural language searches if no modifier is given.
  2. Extended mode
    The extended mode is a modification of the integral mode. The search string is used to perform a natural language search. Then words from the most relevant rows returned by the search are added to the search string and the search is done again. The query returns the rows from the second search.
  3. Boolean mode
    A boolean search interprets the search string using the rules of a special query language. The string contains the words to search for. It can also contain operators that specify requirements such that a word must be present or absent in matching rows, or that it should be weighted higher or lower than usual. Common words such as 'some' or 'then' are stopwords and do not match if present in the search string.
    The following operators are supported:
