Nifi twitter term

KUnew — Wed, 22 Jan 2020 08:00:29 GMT

Hello,

I want to ask what is the proper way to define the terms in Gettwitter processor terms to filter.

I'm trying to retrieve tweets that include the word bt by just writing bt in terms to filter however i'm getting tweets that include the two letters bt in a word such as bt*** or ****bt or ***bt***.

Here is a screenshot of the processor

and this is a sample tweet retrieved by the processor

I just need tweets with the two letters word bt. I tried to use single quote like 'bt' and double quote "bt" but i'm not getting any data

Thank you

Though many of these kind of fields allow regular expressions, the doc for this one does not mention it.

I would try to use a regex, but probably it will not work because the field allows comma separated input.

From here you would need to get creative.

First of all you could definitely add a filter based on a regex afterwards (in Route text).

If this does not perform sufficiently you can perhaps try spaceBTspace but this is obviously a shortcut that will miss some results. (Also I did not test it).

In this particular case BT preceded or followed by a space may capture most cases.

So far the regular recommendations, if you really want to go all the way you could probably create your own get twitter, but I would start with the two step filter and see if it works for you.

I tried to use regex but it didn't work.

Yes the space bt space did really work, I'm thinking to cover other cases by adding space bt & bt space in case they are at the beginning or end of sentence.

Thank you for your help, really appreciate it!
