How do I specify that I do not wish to see apps that require for example internet access? Or to only show apps that use a specific permission?
A specific repository with search on its webpage? An app that provides searching the Play Store?
If you're interested, I've developed an app, StripSearch, to filter search listings by the permissions used. The app works by excluding results that don't meet the permission requirements specified by a given search filter (a filter can exclude, require, or ignore specific permissions). Several filters are included by default, but you can create your own as well.
Get StripSearch here: https://play.google.com/store/apps/details?id=com.hasslefixes.stripsearch
If you want to see a demo explaining its usage, you can watch a video here: https://www.youtube.com/watch?v=mynw3rbky5A
StripSearch is free, does not include ads or spyware, and only uses the following permissions:

How it currently CAN be done
During my morning routine reading my RSS feeds, I stumbled on a review at N-Droid, discussing an app named APEFS. This app is developed by German students (hence its description on the Playstore is in German, even if you set the language to English). But for our non-German readers, a short description here:
Basically, APEFS is an alternative front-end to the Google Playstore. You browse the playstore as you do with the original app, and search it the same. But when on the results list1, an advanced filter2 comes into play:
As the second screenshot shows, you can select what permissions your wanted app is permitted to have (checkbox marked), and what permission it should not have (checkbox unchecked).
However: While this can be used to filter out apps with unwanted permissions (e.g. show only apps whitout the Internet permission), you can not restrict your results to the opposite (e.g. show only apps with Internet permission). The app clearly targets at users concerned about their privacy/security -- and according to the review (I just found it a couple of minutes ago, so I could not test it yet) it does a very good job.
As it's already a year ago, and the promise on the APEFS Homepage (GTransed to English, as their own English version doesn't have that statement in the first paragraph) seems not to be fulfilled anytime soon (the app is still offline): Please consider the web-based solution from my other answer as an alternative meanwhile.
Why currently this can't be done
When a developer performs the upload of his application to Google Play, the application manifest file gets read to a database, from where the search for apps is performed.
To allow searching for applications based on their permissions, one would have to access the database and collect data that concerns the application manifest node
While this seems quite straightforward, Google API does not provide means to this end:
From the Filters on Google Play Filtering based on Manifest Elements - <uses-permission>.
Essentially, Google Play Store uses the application manifest file to automatically apply filters based on the user's device, hardware specifications, country, carrier, etc.
All of this is done silently without the intervention of any search parameters.
A user either from Google Play or third party search engines, can limit the results after they get automatically filtered by Google, based on personal preferences like excluding paid apps; limit the results to apps that are compatible with the user devices, among others. But there's no way to interfere with the filters applied by Google. Even if, some how, we get to that part, the API essentially isn't prepared/designed to filter based on permissions as mentioned above.
More than two years have passed since this question was asked. Still, there's no „official solution” available. Despite its promises, APEFS (introduced in my previous answer over a year ago) has not returned. So I decided to create my own solution:
For almost 4 years now, I maintain listings of „Android apps by purpose”, i.e. grouped by their use cases. In march, I started moving them to my own server. All MetaData are stored in a database on that server, and so finally I was able to setup a search by permissions.
You can select between 1 and 5 categories here (note that selecting a „parent category” automatically includes all its „children”), plus one or more permissions. Default presets are for finding „permission-friendly apps” – so if you're after such a candidate, you can simply submit the form after having made described selections. This should make it easy to e.g. find a PIM app which does not request the Internet permission (to keep your personal data on your device).
However, the opposite is possible as well: If you e.g. want to investigate what good NFC can do for you, select the up to 5 categories you're interested in, then the NFC permission, switch the „Permissions” dropbox to „include”, and optionally the sorting to „by rating, descending” (to get the best-rated apps first).
When in doubt, there's that little question-mark icon in the top-right corner, providing you with some „online help”.
But that's not all. As I've explained in the second paragraph, apps in my lists are grouped by their „purpose”, i.e. what you need them for. So apps with comparable functionality should appear next to each other:
So you can compare them not only by rating, but also pick the one requesting less permissions (number in the box; in above image indicated by a „red 6”) or, if possible, without any concerns (no red border around the box). Clicking the app's name reveals some more details, as shown. And there are many „easter-eggs” (i.e. MouseOver events) – again, be pointed to the help page.
Full disclosure: As initially indicated, the described site was designed by me, built by me, filled by me with its content, and is further maintained by me. It's available bi-lingual (English/German), free of any charge (this includes: no cookies, Flash-cookies, whatever), etc. This question here at Android.SE was one of the reasons I've set it up.
Further be aware of the fact that this doesn't cover the entire „playstore collection”. As of today, there are a little over 10,000 apps recorded in the database (which is probably a little less than 1% of what's on Play – unless you don't count the crap, fakes, and useless apps on Play, then my records might cover about 10% ☺). Still I hope (and think) it's already a useful resource you'll enjoy.
Simple answer: you don't. Though you can feel free to ask Google. As user Chahk said, the web interface saves you a few clicks, but there is still no way to filter results as you are requesting.
A round about way is to create a Java app that utilizes android-market-api. Presently it can search app based on "keywords or package name". The search query can be built to search for the necessary permission that is being sought. Little homework required, but seems useful.
After downloading androidmarketapi-0.6.jar and protobuf-java-2.2.0.jar (of course you should have JRE already setup) you can execute the following:
You have to replace X.Y with 0.6 as that is the present version and replace credentials and query. For building query you can visit this page.
If you have programming skills you can write your own parser and use filters above it. I couldn't find anything about API but you can slowly parse web-interface to get what you want.
It's not the simpliest solution but can make you much confident with results you can get.
Honestly I wish I could make simple example in Python but have no time now. Maybe in nearest future.
Im currently working on a permission based search filter for the Android Play store. For now I have found over 1.2 Mio Apps and added their permission to my database.
The current status can be found here http://live.edgeelement.com/appfilter/
Searching with the permission name still means it searches at best through the description of the app
For example :"COARSE (NETWORK-BASED) LOCATION" -> searching for this will list down applications which have this information listed in their descriptions, but it fails to search through the Permissions tab.
If google allowed to scrape the info of all the apps, like i was, then i would be able to provide the world with a search engine to search apps through permissions they require :)
Per this related answer, this is a great solution:
(I have no affiliation with the app - I had the same question and this was the solution I ended up using).
