Hello, What is placing specific data, such as an IP address, into a field, perhaps called src.ip called? I'm asking so that I can begin to learn by searching. Thank you! ---

I don't know if there's a specific term we use to call it, but the general approach is data processing. ---

I think the word you are looking for is indexing? E.g. I indexed the data into my indices. ---

I think the word you are looking for is **parsing**. For example, from the Merriam-Webster dictionary you have this definition for a _parser_. > a computer program that breaks down text into recognized strings of characters for further analysis Another example, from the description of logstash [json filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html#_description_140). > This is a JSON parsing filter. It takes an existing field which contains JSON and expands it into an actual data structure within the Logstash event. And the same thing for the logstash [grok filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html#_description_134) > Parse arbitrary text and structure it. > Grok is a great way to parse unstructured log data into something structured and queryable. ---

Yeah, that's pretty spot on! ---

Okay! This is helpful. So many responses! Have a great day. I hope I don't have to select just one as The Solution but if I do, and it's not you, it's not personal! ---
