How search works:
  • Punctuation and capital letters are ignored
  • Special characters like underscores (_) are removed
  • Known synonyms are applied
  • The most relevant topics (based on weighting and matching to search terms) are listed first in search results
Topics are ranked in search results by how closely they match your search terms
  • A match on the entire phrase you typed
  • A match on part of the phrase you typed
  • A match on ALL of the terms in the phrase you typed
  • A match on ANY of the terms in the phrase you typed

Note: Matches in titles are always highly ranked.

    Zing indexes words

    Index documents by dividing them into words. Depending on the languages your instance supports, a word may be a single character such as a Chinese or Japanese pictogram or a sequence of characters separated by spaces such as with Latin, Arabic, and Pinyin languages.

    Zing uses spaces to define the basic unit of word separation. Zing uses the following rules to index words.

    Table 1. Zing word indexing rules
    Rule Behavior
    Punctuation Zing indexes some punctuation marks as part of some words to improve search results for common search terms. Zing converts any non-indexed punctuation characters to spaces. See Zing indexes punctuation as part of some words.
    Pictograms Zing supports the full range of Unicode pictogram characters. Each Chinese or Japanese pictogram is indexed as a separate word as if it were a single Latin-1 character surrounded by spaces.
    Letter Zing treats Latin-1, Arabic, and Pinyin characters as individual letters of space-separated-words. Sequences of letters define indexable words.
    • Zing indexes punctuation as part of some words

      Zing indexes some punctuation marks as part of some words to improve search results for common search terms.

    • Zing indexes some HTML elements

      Zing indexes the contents of certain HTML elements to improve document search results. This indexing is addition to the normal indexing by word.

    • Enable text indexing for a table

      Administrators can enable text indexing on a table to allow users to search for string values from table records.

    • Regenerate a text index for a table

      You can regenerate a table text index when you change table stop words or display values.

    • Regenerate a corrupt index

      Typically, a corrupt index regenerates itself. If the system does not start the regeneration process, you must issue a script command to delete the existing index and regenerate it.

    • Remove an index

      You can remove an index if you no longer want the search engine to return results for table.

    • Remove an index for a specific field

      You can remove an index if you no longer want the search engine to return results for a specific field.

    • Change the query mode of an indexed table

      Set the query mode to specify whether searches on an indexed table must match all or only some of the search terms.

    • Text indexing statistics and status

      To view text indexing statistics and status, navigate to System Definition > Text Indexes.

    • Configure tables to use the Japanese tokenizer

      Improve search results in Japanese language searches by configuring individual tables to use the Japanese tokenizer.
