RegExp in Find Definition

Hi,

I have a question regarding regexp usage in find definition (valid for finding reference also).

Here is the use case:
1) I create global database on global 6.4 sources with "gtags -c"
2) I run "global -dx tags." - below is the output:

gtags_close       951 libutil/gtagsop.c gtags_close(GTOP *gtop)
gtags_delete      553 libutil/gtagsop.c gtags_delete(GTOP *gtop, IDSET *deleteset)
gtags_first       681 libutil/gtagsop.c gtags_first(GTOP *gtop, const char *pattern, int flags)
gtags_flush       539 libutil/gtagsop.c gtags_flush(GTOP *gtop, const char *fid)
gtags_next        892 libutil/gtagsop.c gtags_next(GTOP *gtop)
gtags_open        330 libutil/gtagsop.c gtags_open(const char *dbpath, const char *root, int db, int mode, int flags)
gtags_put_using   480 libutil/gtagsop.c gtags_put_using(GTOP *gtop, const char *tag, int lno, const char *fid, const char *img)
gtags_restart     644 libutil/gtagsop.c gtags_restart(GTOP *gtop)
gtags_show_statistics  940 libutil/gtagsop.c gtags_show_statistics(GTOP *gtop)
gtagsexist        142 libutil/getdbpath.c gtagsexist(const char *candidate, char *dbpath, int size, int verbose)
htags_load_filemap  218 htags-refkit/htags_path2url.c htags_load_filemap(const char *filemap)
htags_path2url    266 htags-refkit/htags_path2url.c htags_path2url(const char *path, int line, char *url, int size)
htags_unload_filemap  242 htags-refkit/htags_path2url.c htags_unload_filemap(void)
tagsearch        1733 global/global.c  tagsearch(const char *pattern, const char *cwd, const char *root, const char *dbpath, int db)

I would expect that only

tagsearch        1733 global/global.c  tagsearch(const char *pattern, const char *cwd, const char *root, const char *dbpath, int db)

would be a valid match as it seems the only definition that matches the given regexp.

3) If I run "global -dx .tags" I get:

compare_tags       92 libutil/gtagsop.c compare_tags(const void *v1, const void *v2)
completion_tags   942 global/global.c  completion_tags(const char *dbpath, const char *root, const char *prefix, int db)
createtags        888 gtags/gtags.c    createtags(const char *dbpath, const char *root)
gtags_close       951 libutil/gtagsop.c gtags_close(GTOP *gtop)
gtags_delete      553 libutil/gtagsop.c gtags_delete(GTOP *gtop, IDSET *deleteset)
gtags_first       681 libutil/gtagsop.c gtags_first(GTOP *gtop, const char *pattern, int flags)
gtags_flush       539 libutil/gtagsop.c gtags_flush(GTOP *gtop, const char *fid)
gtags_next        892 libutil/gtagsop.c gtags_next(GTOP *gtop)
gtags_open        330 libutil/gtagsop.c gtags_open(const char *dbpath, const char *root, int db, int mode, int flags)
gtags_put_using   480 libutil/gtagsop.c gtags_put_using(GTOP *gtop, const char *tag, int lno, const char *fid, const char *img)
gtags_restart     644 libutil/gtagsop.c gtags_restart(GTOP *gtop)
gtags_show_statistics  940 libutil/gtagsop.c gtags_show_statistics(GTOP *gtop)
gtagsexist        142 libutil/getdbpath.c gtagsexist(const char *candidate, char *dbpath, int size, int verbose)
htags_load_filemap  218 htags-refkit/htags_path2url.c htags_load_filemap(const char *filemap)
htags_path2url    266 htags-refkit/htags_path2url.c htags_path2url(const char *path, int line, char *url, int size)
htags_unload_filemap  242 htags-refkit/htags_path2url.c htags_unload_filemap(void)
start_ctags        92 plugin-factory/exuberant-ctags.c start_ctags(const struct parser_param *param)
start_ctags       161 plugin-factory/exuberant-ctags.c start_ctags(const struct parser_param *param)
terminate_ctags   136 plugin-factory/exuberant-ctags.c terminate_ctags(void) {
terminate_ctags   206 plugin-factory/exuberant-ctags.c terminate_ctags(void)
updatetags        799 gtags/gtags.c    updatetags(const char *dbpath, const char *root, IDSET *deleteset, STRBUF *addlist)

Same as above, I would expect that only

gtags_close       951 libutil/gtagsop.c gtags_close(GTOP *gtop)
gtags_delete      553 libutil/gtagsop.c gtags_delete(GTOP *gtop, IDSET *deleteset)
gtags_first       681 libutil/gtagsop.c gtags_first(GTOP *gtop, const char *pattern, int flags)
gtags_flush       539 libutil/gtagsop.c gtags_flush(GTOP *gtop, const char *fid)
gtags_next        892 libutil/gtagsop.c gtags_next(GTOP *gtop)
gtags_open        330 libutil/gtagsop.c gtags_open(const char *dbpath, const char *root, int db, int mode, int flags)
gtags_put_using   480 libutil/gtagsop.c gtags_put_using(GTOP *gtop, const char *tag, int lno, const char *fid, const char *img)
gtags_restart     644 libutil/gtagsop.c gtags_restart(GTOP *gtop)
gtags_show_statistics  940 libutil/gtagsop.c gtags_show_statistics(GTOP *gtop)
gtagsexist        142 libutil/getdbpath.c gtagsexist(const char *candidate, char *dbpath, int size, int verbose)
htags_load_filemap  218 htags-refkit/htags_path2url.c htags_load_filemap(const char *filemap)
htags_path2url    266 htags-refkit/htags_path2url.c htags_path2url(const char *path, int line, char *url, int size)
htags_unload_filemap  242 htags-refkit/htags_path2url.c htags_unload_filemap(void)

are shown as the regexp ".tags" matches only these.

Same is observed with finding references also.

Am I missing something?

Thanks,
Best Regards,
Pavel
