  • billkarwin Karwin Software Solutions LLC at Karwin Software Solutions LLC Andrés, thanks, I'm glad the presentation was helpful to you. As for your question, see this excerpt from http://www.postgresql.org/docs/8.4/static/textsearch-intro.html#TEXTSEARCH-MATCHING:

    'The @@ operator also supports text input, allowing explicit conversion of a text string to tsvector or tsquery to be skipped in simple cases. ... The form text @@ text is equivalent to to_tsvector(x) @@ plainto_tsquery(y).'

  • apachon1 Andrés Pachon Thank you so much for such a great and self explanatory presentation! Just one last question:

    Not sure if it was a typo, but the query specified in slide #21 doesn't throw any results. Shouldn't it be modified to the following?

    SELECT * FROM Posts WHERE PostText @@ to_tsquery('postgresql & performance')

    Thank you!
