Hello, and welcome to this short lecture
大家好，欢迎大家学习这个很短的教学 (CG教学翻译网 听译培训学员 肖黎山 试译作品)
well, I'll just mention a few things about the query string approach
before I'll move on to show you how to search with query DSL
fistly, I want to mention that any special characters that you include in the query string must be escaped with backslash
special characters are any that have meaning to elastic search
such as parentheses, plus, minor and equal signs.
question marks etc. Now there are more features available to you if you are using the query strings approach for your searchs
We will get back to some of it in the following lectures
but if you have a use case that can not be solved with what we'll work through in the proceeding lectures,
then I encourage you to check out the documentation on query searches
If that also doesn't help, then you can post it to course disscusion.
and I'll do my best to help you,
you should now have an overall understanding on how to perform searchs with query searches in the elastic seach.
In the next lecture, we will take a look at searching with query DSL
which is the other way of searching in elastic search
until then, happy searching.
