Support query clauses

[DanieleFedeli]

Targets #15 Functionality is ready. I need some benchmarks and to resolve conflicts.

@micheleriva Benchmarks:

Honestly, I am not happy with the range of query results. Right now I do a linear search over keys. I will try something non-linear.

[DanieleFedeli]

Thank you @anonrig I will work on that soon :clinking_glasses:

[DanieleFedeli]

Managed to get a better benchmark by changing the index data structure.

I will solve the conflicts, adjust the document deletion and I'm done.

Hi @micheleriva, Is there something wrong with this PR? I can fix it if that is the case

[micheleriva]

Hey @DanieleFedeli, I'm putting this PR on hold until we merge a major change from the simple-structures branch

[DanieleFedeli]

Ok, please write a comment when we can merge this so I will resolve conflicts

[DanieleFedeli]

@micheleriva May I start developing the plugin?

[micheleriva]

@DanieleFedeli we're still working on the hooks system, I'd recommend waiting for it as it would simplify the work by a lot 🙏

[DanieleFedeli]

@micheleriva I have been busy this period, I did not follow Lyra.

~Are hooks integrated?~ I saw that only an insert hook is available. Is it planned to have more hooks? I think for this feature I will need for example:

• onSearch to make the intersection between Lyra normal result and the plugin one
• onDelete to remove the indexes of the deleted document
