-******************************************************************************
-**
-** This file contains test code only, it is not included in release 
-** versions of FTS5. It contains the implementation of an FTS5 auxiliary
-** function very similar to the FTS4 function matchinfo():
-**
-**     https://www.sqlite.org/fts3.html#matchinfo
-**
-** Known differences are that:
-**
-**  1) this function uses the FTS5 definition of "matchable phrase", which
-**     excludes any phrases that are part of an expression sub-tree that
-**     does not match the current row. This comes up for MATCH queries 
-**     such as:
-**
-**         "a OR (b AND c)"
-**
-**     In FTS4, if a single row contains instances of tokens "a" and "c", 
-**     but not "b", all instances of "c" are considered matches. In FTS5,
-**     they are not (as the "b AND c" sub-tree does not match the current
-**     row.
-**
-**  2) For the values returned by 'x' that apply to all rows of the table, 
-**     NEAR constraints are not considered. But for the number of hits in
-**     the current row, they are.
-**     
-** This file exports a single function that may be called to register the
-** matchinfo() implementation with a database handle:
-**
-**   int sqlite3Fts5TestRegisterMatchinfo(sqlite3 *db);
