In the case of a search service disruption the status updates will be shown here.
05 Jun 26: There was an attempt to release v7.8.1 with change in search service protocol, but I noticed something is maybe wrong with the server management version (derivative of UE) and reverted all back out of abundance of caution, it was available for at most 20 minutes. If you downloaded it during the short time period (after trying to use the search service since I didn't set the update notification) downgrade to v7.8 since there is no clear UE notification when the search protocol has been possibly downgraded (which will be now added, since I didn't foresee such scenario, it will be something positive to come out of this). It might be very few users in single digits who are affected. The message will be removed after I sort it out and make the release now maybe as v7.8.2. It is also possible that it is nothing, in such a case v7.8.1 will be reinstated.
i just keep the search syntax so one can make complex searches at the expense of reading the short explanation about boolean wildmats in help notes, these are a little more than wildcards, not regular expressions (i hate regular expressions). it would be much simpler to implement the indexing without complex search pattern capability.
