Does "termFreq" has the capability to search for the word frequency from two corpora simultaneously?

Hello, I'm currently using BlackLab for corpus retrieval. I'd like to know if BlackLab api "termFreq" has the capability to search for the word frequency of the most common words , such as top 20 words in Corpus A and top 20 words Corpus B, and then provide the total word frequency of top 20 words across both corpora (Maybe top 20 words in CorpusA, corpusB and corpusA&B are not same). I once considered separately counting the word frequencies of all words in corpus A and corpus B in my script and then calculating the total word frequency, but I'm concerned that this may slow down my retrieval speed. Thank you very much!

BlackLab's search operations always work on a single corpus only.

You can perform two termfreq operations, one on each corpus, at the same time, and then combine the results using a script. Depending on the hardware you're running on, you might run into bottlenecks (I/O, CPU or memory) if you run multiple requests at once.
