MarkLogic 9 Product DocumentationWordsSearch functions (WordsSearch)
Use these functions to query and compute aggregates over words in a
word lexicons. Create a words query builder using
jsearch.words, then build up the query by chaining
calls to methods such as where and orderBy.
Finally, execute the query by calling the result method.
To use this module in your Server-Side JavaScript code, include a
require statement similar to following line in your code:
const jsearch = require("/MarkLogic/jsearch");
The order in which you call the methods of this class is significant. You should preserve the order shown in the template below. For details, see Query Design Pattern in the Search Developer's Guide.
Use the following form for querying the values in a lexicon or range
index. All the calls except jsearch.words and
result are optional.
jsearch.words(jsonPropNamesOrWordLexiconRefs)
.where(queries)
.match(pattern)
.orderBy(orderingConfig)
.slice(startPos, endPosPlusOne)
.map(funcRef) | .reduce(funcRef, optionalSeed)
.withOptions(optionsConfig)
.result()
For details, see jsearch.words, WordsSearch, and Querying Values in a Word Lexicon in the Search Developer's Guide.
