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 can expand search results with synonyms

    Expand search results to include additional search terms.

    By default, Zing includes a sample synonym dictionary consisting of a list of synonym sets (synsets). Zing supports two types of synonym sets.
    Table 1. Synonym set types
    Synonym set type Description Example
    Synonym list A synonym list is a list of words separated by commas. When a search uses any word from the list, Zing expands the search to include all words in the list. Cyber,Internet,Cybercafe
    Synonym map A synonym map is two word lists separated by the equal and greater than characters => . When a search uses any word from the list on the left, Zing expands the search to include all words from the list on the right. When a search uses a word from the list on the right, Zing does not expand the search to include terms from the list on the left. IOT,Internet of Things=>Chip,Nest thermostat,RFID,IOT

    Search administrators can create synonym sets for search terms that produce no or low-scoring search results. See the Top Searches homepage for information about your user's search behavior.

    Search results, synonym expansion and weighting

    In search results, documents containing the original search keywords having a higher score than documents containing the search synonyms. For example, documents with the keyword IOT have a higher score than documents with the synonym Internet of Things.
    • One-way synonym expansion to/from multiple terms (blork, cork => malork, elastic) works as expected. Blork and cork both expand to malork and elastic.
    • Multi-level one-way expansion (blork => cork => malork) does not work transitively. Neither blork nor cork expands to malork.
    • Multi-level one-way expansion split between multiple synonym set records (blork => cork)(cork => malork) does not work transitively. Only cork expands to malork, blork only expands to cork but not malork.

    By default, synonyms do not use the same weight as regular search terms. Synonyms are only weighted at 10% of the default search weight. Additionally, multiple instances of a synonym in a single doc/field do not increase the search weight. The weight of synonyms is controlled by the property glide.ts.synonym.expanded.boost. When this property value = 1, synonyms are weighted equally to normal search terms. 0.5 = 50% weight etc.

    • Enable search synonyms

      Enabling text index synonyms allows Zing to expand text searches with additional search keywords.

    • Create synonym dictionaries

      You can create synonym dictionaries to expand text searches with additional search keywords.

    • Select synonym dictionaries for a table

      Search administrators can specify one or more synonym dictionaries available to a particular table.

    • Disable synonyms for a table

      By default, Zing uses all active synonym dictionaries when a user performs a text search. Search administrators can disable synonym dictionary usage on a per-table basis.

    • Debug synonym searches

      You can view debug messages to determine if synonym searches are working as expected.
