2021-01-31 [0c4f355c6] Fix parsing of complex morphs to tsquery
-->
<para>
Fix to_tsquery() and websearch_to_tsquery() to properly parse certain discarded tokens in quotes (Alexander Korotkov)
</para>
<para>
Certain discarded tokens, like underscore, caused the output of these functions to produce incorrect tsquery output, e.g., websearch_to_tsquery('"pg_class pg"') used to output '( pg &amp; class )
&lt;-&gt; pg',but now outputs 'pg &lt;-&gt; class &lt;-&gt; pg'.

Make websearch_to_tsquery() parse text in quotes as a single token (Alexander Korotkov)
Fix websearch_to_tsquery() to properly parse multiple adjacent discarded tokens in quotes (Alexander Korotkov)
</para>
<para>
DETAILS? ALREADY CHANGED ABOVE.
Previously, quoted text that contained multiple adjacent discarded tokens were treated as multiple tokens, causing incorrect tsquery output, e.g., websearch_to_tsquery('"aaa: bbb"') used to output
'aaa &lt;2&gt; bbb', but now outputs 'aaa &lt;-&gt; bbb'.
