well, i did some experiments, and here is the result :
to install this mod, you can use AUTOMOD plugin, which is downloadable via phpbb.com site, and which allows you to install modX mods ...
it will NOT install if you are using by default other than EN language, because it wont find language/YOURLANG files. Simply solution : copy and paste the EN subfolder in the plugin as for example DE subfolder, if you use german language, etc ... the text will be in english, but at least your installation and ACP will work
latest version of sphinx under SUSE enterprise linux doesnt have "indexer" and "searchd" binaries, but
"sphinx-indexer" and "sphinx-searchd", so this will be problem for this mod as well. Go to your /usr/bin directory (or where you have your sphinx binaries) and create symbolic links
ln -s sphinx-indexer indexer
ln -s sphinx-searchd searchd
to create the shortcuts named "indexer" and "searchd".
if you are already using sphinx with other applications, and you do not want to mess up with it, go to ACP and change PORT and PATH to config file of phpbb sphinx, so it doesnt collide with your existing sphinx settings.
so far, sphinx works on my site, with just one problem
as our site is plastic model kits focused site, I need to do a lot of searches for airplanes and tanks with "-" in its name : F-16, T-34, F-22 Raptor etc ... on my site, im using the EXTENDED type of sphinx search, and i convert the search from
using this, i just send it to the search and get results. But, with sphinx-phpbb, it doesnt work. With quotes or without them, same result. What can I do to pass the EXACT value that has been typed to search field, to sphinx search ? without any alterations, replacements, etc ? or is there any other way, how to make names like T-34 work in this mod ?
