Coding Week 3: Working Holiday

Beginning of week was really exciting as previous week i haSo it was The time to get back to coding again and implement the proposal.So it was The time to get back to coding again and implement the proposal.d Treaking Exploration With Xapian code and prepared so called Bi-gram Integration Proposal.And asked for the feedback from the community about the  Proposal from community.

So it was The time to get back to coding again and implement the proposal.

I started working as proposed by me in proposal as no  one responded on proposal.And this was my biggest mistake!!!!

What i did (Implemented) :

1.  Bigram Iterator.
2.  Bigram PostList
3. Stores terms of document in termlist table with a different key than normal terms to treat bi-grams in backend differently than uni-gram,so that we can access terms of document fairly easily
4. Adjusted Postlist to store without any changes as backend postlist table storage have term as keys.so it doesn't require a different key.

Didn't understand what i did? referring this might help: Bigrams

After completing the work i informed informally Olly Betts(My Saviour) that  this is what i did.He told me its better to treat Bigrams as terms and i was convinced that we should keep it separate mainly due to two reasons:

1.  I thought it was best to keep them separate as it would be easy to access later.
2.  Keeping them as term would all implementation a big waste and i thought if we have them separate then why to make them a mess and keep together.

I spent a full day arguing with Olly Betts about we should keep them separate.But finally Olly said:

"olly: I guess we are going over a circle without quite understanding each other"

So, then i decided to discard my implementation and treat them as terms.With some  more discussion to understand why we store them together Olly told me we don't really use these frequently and moreover backend dont need to know which are bi-grams and which are uni-grams.Application can check which are bigrams easily and it won't decrease performance as it rarely done process to open termlist of document.

So it seemed a good reason to treat them same.And i discarded my whole implementation  and started a fresh.So in all i learned and had fun  coding this week but no useful work making it a Working Holiday.

Free Advice for readers(if any) :P:

1. Never Start foundation implementation before discussion on every bit with mentor or concerned members.
2. Try to understand other and do question wisely(to solve doubts) than circling over a problem.
