Another parser for advanced search query syntax.
npm install search-string> Another simple parser for advanced search query syntax.
 
It parses typical Gmail-style search strings like:
``
to:me -from:joe@mixmax.com foobar1 -foobar2
And returns an instance of SearchString which can be mutated, return different data structures, or return the gmail-style search string again.
See this blog post introducing this library.
`shell`
$ npm install search-string
`javascript
const SearchString = require('search-string');
// Perform parsing
const str = 'to:me -from:joe@mixmax.com foobar1 -foobar2';
const searchString = SearchString.parse(str);
/ Get text in different formats. /
// [ { text: 'foorbar1', negated: false }, { text: 'foobar2', negated: true } ]
searchString.getTextSegments();
// foobar1 -foobar2
searchString.getAllText();
/ Get conditions in different formats. /
// Standard format: Condition Array
// [ { keyword: 'to', value: 'me', negated: false }, { keyword: 'from', value: 'joe@mixmax.com', negated: true } ]
searchString.getConditionArray();
// Alternate format: Parsed Query
// { to: ['me'], excludes: { from: ['joe@mixmax.com'] }}
searchString.getParsedQuery();
/ Or get text and conditions back in string format. /
// to:me -from:joe@mixmax.com foobar1 -foobar2
searchString.toString();
/ Mutations exist as well for modifying an existing SearchString structure. /
// to:me foobar -foobar2
searchString.removeKeyword('from', true).toString()
// to:me from:jane@mixmax.com foobar1 -foobar2
searchString.addEntry('from', 'jane@mixmax.com', false).toString();
// from:jane@mixmax.com foobar1 -foobar2
searchString.removeEntry('to', 'me', false).toString();
/ clone operation instantiates a new version by copying over data. /
// from:jane@mixmax.com foobar1 -foobar2
searchString.clone().toString();
