# Text::Query::ParseSimple(3pm)

Parse AltaVista simple query syntax

## NAME

Text::Query::ParseSimple - Parse AltaVista simple query syntax

## SYNOPSIS

```
  use Text::Query;
  my $q=new Text::Query('hello and world',
                        -parse => 'Text::Query::ParseSimple',
                        -solve => 'Text::Query::SolveSimpleString',
                        -build => 'Text::Query::BuildSimpleString');
```

## DESCRIPTION

This module provides an object that parses a string   containing a Boolean query expression similar to an AltaVista "simple  query". Elements of the query expression may be assigned weights.

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

Query expressions are compiled into an internal form when a new object is  created or the `"prepare"` method is called; they are not recompiled on each  match.

Query expressions consist of words (sequences of non-whitespace)   or phrases (quoted strings) separated by whitespace.  Words or phrases  prefixed with a `"+"` must be present for the expression to match; words or  phrases prefixed with a `"-"` must be absent for the expression to match.

Words or phrases may optionally be followed by a number in parentheses (no  whitespace is allowed between the word or phrase and the parenthesized  number).  This number specifies the weight given to the word or phrase. If a weight is not given, a weight of 1 is assumed.

## EXAMPLES

```
  use Text::Query;
  my $q=new Text::Query('+hello world',
                        -solve => 'Text::Query::SolveSimpleString',
                        -build => 'Text::Query::BuildSimpleString');
  die "bad query expression" if not defined $q;
  $count=$q->match;
  ...
  $q->prepare('goodbye adios -"ta ta"', -litspace=>1);
  #requires single space between the two ta's
  if ($q->match($line, -case=>1)) {
  #doesn't match "Goodbye"
  ...
  $q->prepare('\\bintegrate\\b', -regexp=>1);
  #won't match "disintegrated"
  ...
  $q->prepare('information(2) retrieval');
  #information has twice the weight of retrieval
```
