  8. <code class="command">CREATE TEXT SEARCH CONFIGURATION</code> creates a new text
  9. search configuration. A text search configuration specifies a text
  10. search parser that can divide a string into tokens, plus dictionaries
  11. that can be used to determine which tokens are of interest for searching.
  12. </p><p>
  13. If only the parser is specified, then the new text search configuration
  14. initially has no mappings from token types to dictionaries, and therefore
  15. will ignore all words. Subsequent <code class="command">ALTER TEXT SEARCH
  16. CONFIGURATION</code> commands must be used to create mappings to
  17. make the configuration useful. Alternatively, an existing text search
  18. configuration can be copied.
  19. </p><p>
  20. If a schema name is given then the text search configuration is created in
  21. the specified schema. Otherwise it is created in the current schema.
  22. </p><p>
  23. The user who defines a text search configuration becomes its owner.

  34. The <code class="literal">PARSER</code> and <code class="literal">COPY</code> options are mutually
  35. exclusive, because when an existing configuration is copied, its
  36. parser selection is copied too.
