I use Aliyun"s ECS with 1G memory, and the configuration is slightly lower. I originally wanted to install an elasticsearch to realize full-text index search, but the software elasticsearch was developed by java. It seems that the software developed by java is a large memory user, so I think of xunsearch instead, but I don"t know much about this. I hope to have great help to see if I can install xunsearch in this configuration. My cloud host has 40 gigabytes of hard disk space and more than 5000 items of index data. Article consultation type of the website.
