I was thinking that the implication of the attribute in the htdig command could come about by means of a library or perhaps some other file which referenced it and was part of htdig although not in the htdig sub-directory's source files but, yes, it doesn't really affect htdig. > > A repetition of the tests I ran before confirms that a database created by > > "rundig -a" with an htdig.conf file with the line > > > > search_algorithm: substring:0.5 > > > > can be searched for strings other than whole words by htsearch using the sa me > > That is because *htsearch* is now using the htdig.conf *with* > substring:0.5. > > > htdig.conf file while a database created by "rundig -a" with an htdig.conf file <snip> > > rundig with these two htdig.conf files are the same size.

That seems to be the upshot of the documentation and I found that htfuzzy didn't change the modification date or the cksums of the database files. > > In trying to pin down whether htdig or htpurge or both had to be run with t he > > htdig.conf file with the search_algorithm: line, I found that specifying th e > > alternate htdig.conf file with "-c <file name>" didn't have the same effect > It is hard to say what exactly is going on here because the important bit > is which configuration file you used with htsearch, not rundig.

That became clear to me when I ran some more tests and eventually found that the form I was using for htsearch wasn't having the intended effect of using the sub-string version of htdig.conf regardless of which file had been named "htdig.conf". My earlier tests had been based on that assumption. The confusion resulted from the fact that I used the "-c" flag to specify an alternate conf file for htdig, htpurge, and rundig while for htsearch I used the HTML form. Would it be possible to call htsearch with the "-c" flag from an HTML form? I suppose that, if that is possible, doing so would preclude the possibility of the user's deciding on the search form whether he wants string or whole-word searching.
