SYNOPSIS

  use Text::Query;
  my $q=new Text::Query('hello and world',
                        -parse => 'Text::Query::ParseAdvanced',
                        -solve => 'Text::Query::SolveAdvancedString',
                        -build => 'Text::Query::BuildAdvancedString');

DESCRIPTION

It's base class is Text::Query::Parse;

Query expressions consist of literal strings (or regexps) joined by the following operators, in order of precedence from lowest to highest:

OR, |

AND, &

NEAR, ~

NOT, !

Operator names are not case-sensitive. Note that if you want to use a "|" in a regexp, you need to backwhack it to keep it from being seen as a query operator. Sub-expressions may be quoted in single or double quotes to match "and," "or," or "not" literally and may be grouped in parentheses ("(, )") to alter the precedence of evaluation.

A parenthesized sub-expression may also be concatenated with other sub- expressions to match sequences: "(Perl or Python) interpreter" would match either "Perl interpreter" or "Python interpreter". Concatenation has a precedence higher than NOT but lower than AND. Juxtaposition of simple words has the highest precedence of all.

OPTIONS

-near defaults to 10

Sets the number of words that can occur between two expressions and still satisfy the NEAR operator.

-operators defaults to and, or, not, near

Sets the operator names. The argument of the option is a pointer to a hash table mapping the default names to desired names. For instance:

    {
        'or' => 'ou',
        'and' => 'et',
        'near' => 'proche',
        'not' => 'non',
    }
    

-scope_map default to {}

Map the scope names to other names. If a scope is specified as "scope:" search the map for an entry whose key is "scope" and replace "scope" with the scalar found. For instance:

     {
         'scope' => 'otherscope'
     }
