Searching Full-text with ArangoSearch

Search for tokens in full-text that can occur in any order

Full-text strings can be tokenized by text Analyzers so that each token (usually a word) gets indexed separately. Subsequently, it becomes possible to search for individual tokens. This is also possible with arrays of strings, where each element is one token (or multiple, additionally tokenized by a text Analyzer).

There are two ways to search for tokens:

  • Token search: The tokens can occur in any order. The words you search for merely need to be contained in the source string somehow.
  • Phrase search: The order of the tokens needs to match the query. This allows you to search for partial or full sentences.

Token search is covered below. For phrase search see Phrase and Proximity Search.

    description: doc.description
  }

Search for movies with both dinosaur and park in their description:

FOR doc IN imdb
  SEARCH ANALYZER(TOKENS("dinosaur park", "text_en") ALL == doc.description , "text_en")
  RETURN {
    title: doc.title,
    description: doc.description
  }

The results will be the same if you use park dinosaur as search terms, as the tokens can be ordered arbitrarily.
