Overview

TEXTML Server allows you to construct two types of queries.

• Document queries that retrieve documents. Almost of the queries in this documentation are document queries.
• Indexed value queries that retrieve the list of values in an index. For example, from a FullText index of all the words in a docbase, an Indexed value query retrieves a list of all the words that are currently indexed.

The elements you can use in XML queries are:

• Keys: references to the indexes in which the search is performed.
• Operators: elements that join two searched values.
• Wildcards: elements that replace characters or strings.
• Results and Result spaces: Container objects used to store and manipulate data retrieved by a search.

The data types of the search terms in a query are the same as for an index: words, strings, dates, times and numbers.

For the complete syntax of the two types of queries, see the following two DTDs (Document Type Definitions):

• Document queries: SEARCH_DOCUMENTS.DTD
• Indexed value queries: SEARCH_DOCUMENTS.DTD

For a query that will retrieve all DTDs and other system documents from a docbase (including the sample docbase that you can create using documents and Index Definition document), see Retrieving all DTDs and other system documents
