Which issue does this PR fix?:
fixes: #65 #70

This PR resolves issue #70 (The random keywords in search box aren't always having a search result). Following is obtained upon typing "Logistic Regression" onto the searchbox.

The above search displays the correct results.
However, following is obtained upon typing "logistic regression" (which is basically one of the randomly generated keywords which show up upon launching Cosmos Search).

Finally, following is obtained upon typing "logistic regression" after widening the search scope a bit.

This PR also resolves the pluralization issue.

Why do we need this PR?:

Most users expect the same results while searching for "Logistic Regression", "logistic regression" etc. The search should be able to handle such cases. We aim to broaden the search experience of users through this PR and the PRs that follow.

@AdiChat Please review.

@xx621998xx I have already sent PR for the issue #65.

[sarthikadhawan]

@sakshee-19 That's cool!
This PR majorly focuses on query optimization (#70) as discussed, so no issues (pun intended). :D

Nice work 👍

The issue (#70) is related to keywords like hierachical clustering which is not being considered by the current implementation. Note that, we get results for hierachical-clustering.

You have capitalized the first letters but this could be avoided by doing a matching after converting both data to lowercase. Instead, you must generate permutation in terms of order of words and separate them with _ and -.

Note that linear search returns a result but search linear does not.
Thus, for keyword linear search, the permutations generated must be linear_search, linear-search, search_linear and search-linear.

Kindly make appropriate changes and let us know when it is ready for review. 👍

@AdiChat I think we should always replace - with _ to reduce complexity of search strategy.
In this way, we can just change metadata generator in update/view.py.

If you agree, I will implement this.

[sarthikadhawan]

@iattempt , we have already started working on the issue :)

[soc221b]

In my opinion, we should sort combinations by length and/or else.
In general, one want get the most matched result with the tags she/he typed.

[AdiChat]

@iattempt Sure. I guess you are suggesting to remove the inconsistency in Cosmos structure and update the metadata generator. This will be great. 👍

@xx621998xx You can continue working on this issue, assuming, - has been replaced by _.
Thus, for keyword linear search, the permutations generated must be linear_search, search_linear, linear and search. The final result should be the one having the minimum positive number of results. 👍

[soc221b]

I think we should extract/refactor class by the function query in search/views.

Could I work on this?

[AdiChat]

@iattempt Sure, Go for it 👍
