We are happy to announce a Solar-powered search engine on our web site. The search is integrated with the site, so click on the right upper icon to open the search box, type your words and the search will be far more relevant.
Use “+” and “-” to do precise searching like this example focused on Arduino and Z80.
Also Solar “facetting” is supported on the right sidebar:
We tried Elastic Search first. Elastic Search documentation is well written and overall package is a lot refined. For instance the jvm configuration is very well written, with Garbage collection tuning. Also there are different options for JDK 8,9 and 10. At boot time the system do some sanity checks.
But we failed to find a working wordpress plugin for elastic search: the installation was a pain.
Apache Sol(a)r has a lot less wordpress plugins, but seems easier to set up.
By the way, comparing ElasticSearch and Solr we found a lot less memory hungry the latter. For indexing 1000s articles, we squeezed solar with less then 320 MegaBytes and it is working fine, so far.
