Creating a knowledge base in dialogflow with java API - dialogflow-es

I need to create a knowledge base and add some question/answer data there. I went through this example https://github.com/dialogflow/dialogflow-java-client-v2/blob/master/samples/src/main/java/com/example/dialogflow/KnowledgebaseManagement.java but that apparently just creates an empty knowledge base.
Tried digging through the (very poor) documentation available but found no way to make it actually do something useful.

Need to jump through these hoops

Pyperplan with action costs support or alternative wanted

I'm using pyperplan in my project, however I'm very limited in choice of planning domains, as pyperplan does not support PDDL v2
Do you know of any pyperplan fork, that has this functionality? Basic +1 action costs should be enough, they are my only problem right now.
Eventually, do you know of any pyperplan-ish alternative that would support more modern versions of PDDL?
I'm planning to implement the functionality on my own, I ran through the code, and it shouldn't be THAT hard, it looks pretty set up for that.
I went through all forks listed on github, but none of them has this feature. I've also tried looking up such clone myself, or looking up any related articles, but nothing of value showed up.
I will be really grateful for any tips!

How to create expansion panels with MDC web?

They have it in their List Documentation and in their Design Guideline as "Expansion Panels" but not in their List Demo.
Technically, this is what I want, but it's not specified how to get there and how to actually use it. My question is how and if this can be done. I have found multiple older issues discussing this and my hope is that it just didn't make it into the docs yet.
For everybody who finds this and just wants a solution that's not necessarily material design:

style guide from the official docs. (you still have to implement these yourself)

Semantics based code search

We have a large number of repositories. We want to implement a semantics(functionality) based code search on those repositories. Right now, we already have implemented keyword based code search in which we crawled through all the repository files and indexed them using elasticsearch. But that doesn't solve our problem as some of the repositories are poorly commented and documented, thus searching for specific codes/libraries become difficult.
So my question is: Is there any opensource libraries or any previous work done in this field which could help us index the semantics of the repository files, so that searching the code becomes easy and this would also help us in re-usability of the codes. I have found some research papers like Semantic code browsing, Semantics-based code search etc. but were of no use as there was no actual implementation given. So can you please suggest some good libraries or projects which could help me in achieving the same.
P.S:-Moreover, companies like Koders, Google, cocycles.com etc. started their code search based on functionality. But most of them have shut down their operations without giving any proper feedback, can anyone please tell me what kind of difficulties they are facing.
not sure if this is what you're looking for, but I wrote https://github.com/google/zoekt , which uses ctags-based understanding of code to improve ranking.
Take a look at insight.io
It provides semantic search and browsing

Is there a typical config or property file format and library in Haskell?

I need a set of key-value pairs for configuration read in from a file. I tried using show on a Data.Map and it doesn't look at all like what I want. It seems this is something many others might have already done so I'm wondering if there is a standard way to do it and what library to use.
Go to hackage.
Click on "packages"
Search for "config".
Notice ConfigFile(TH), EEConfig, and tconfig.
Read the Haddock documentation
Select a couple and implement your task.
Blog about your findings so the rest of us can learn from your new found expertise (thanks!).
EDIT:
I've recently used configurator - which was easy enough. I suggest you try that one!
(Yes, yes. If I took my own advice I would have made a blog for you all)
The configuration category on Hackage should list all relevant libraries:
http://hackage.haskell.org/packages/#cat:Configuration
I have researched the topic myself now, and my conclusion is:
configurator is very good, but it's currently only for user-edited configurations. The application only reads the configuration and cannot modify it. So it's more for server-side applications.
tconfig has a a simple API and looked like it was what I wanted, maybe a bit raw, until I realized it's unmaintained and that some commits which are really important to use the app are applied on github but the hackage package was not updated
Other solutions didn't look like they'd work for me, I didn't like the API, but every application (and tastes) are different.
I think using JSON for instance is not a good solution because at least with Aeson when you add new settings in a new release, the old JSON without the new member from the previous version won't load. Also, i find that solution a bit verbose.
The conclusion of my research is that I wrote my own library, app-settings, which aims to be key-value, read-write, with a as succint and type-safe API as possible. And you'll find it also in the hackage links for the configurations category that I gave.
So to summarize, I think configurator is the standard for read-only configurations (and it's very powerful too, you can split the configuration file with imports for instance). For read-write there are many small libraries, some unmaintained, and no real standard I think.
UPDATE 2018 be sure to look at dhall
I'd also suggest just using Text.JSON or one of the yaml libraries available (I prefer JSON myself, but...).
The configfile package looks like what you want.

Does anyone know where decent documentation describing the Lucene index format IN DETAIL on the web is?

I am mainly curious as to the inner workings of the engine itself. I couldnt find anything about the index format itself (IE in detail as though you were going to build your own compatible implementation) and how it works. I have poked through the code, but its a little large to swallow for what must be described somewhere since there are so many compatible ports to other languages around. Can anyone provide a decent link?
Have you seen this: http://lucene.apache.org/java/2_4_0/fileformats.html? It's the most detailed I've found.
Although Lucene in Action does stop short of the detail in that link, I found it a useful companion to keep a handle on the big picture concepts while understanding the nitty gritty.
