I'm writing a webapp that uses the YouTube Code API to do specific types of searches. In this case, I'm trying to search for all videos that match a query, and which were uploaded between two dates. This document says I can use published-min and published-max parameters, while this one says I can use updated-min and updated-max.
Both of these parameter sets cause YouTube to return an error:
published-min returns "This service does not support the 'published-min parameter"
updated-min returns "This service does not support the 'updated-max' parameter"
With neither returns a correct result set.
How can I limit my result set to hits within a specified date range?
The Reference Guide for YouTube's Data API doesn't list anything that would suggest the possibility to filter on time interval in general.
The published-min argument is only advertised in the "User activity feeds" section which is something different and probably not the thing you wanted. Or is it?
The updated-min argument in your link is referenced in a generic gdata context. It looks like they intended to describe all the things common to all the specialized APIs, but somehow updated-min isn't available everywhere.
When it comes to your very problem. I would suggest sorting on time (orderby=published) and do the filtering on the client side. I know this is not the optimal way, but the only one I can see with what Google gives us.
youtube api v3 supports publishedAfter and publishedBefore parameters with search results. For example:
https://www.googleapis.com/youtube/v3/search?key={{YOUKEY}}&channelId={{CHANNELID}}&part=snippet,id&order=date&maxResults=50&publishedAfter=2014-09-21T00:00:00Z&publishedBefore=2014-09-22T02:00:00Z

https://api.bing.microsoft.com/v7.0/spellcheck?text=mus&mkt=en-GB&mode=spell
Using the above URL and given my supplied API key within the request headers - I am getting no results back from the Bing Spell Checker API using PostMan or from Refit in C#(Xamarin Forms).
For 'mus' I'm expecting 'must', for 'tst' I'm expecting 'test' but, neither seem to work.
I've set the mode to 'spell' which should be the case however, even in 'proof' mode it doesn't return any results.
Please can somebody let me know why?
Thanks
The documentation explains:
Bing Spell Check API lets you perform contextual grammar and spell checking on a text string. While most spell-checkers rely on dictionary-based rule sets, the Bing spell-checker leverages machine learning and statistical machine translation to provide accurate and contextual corrections.
I assume that passing single words in most cases won’t provide enough information for this approach.
Try passing phrases that put your words in some reasonable context like mst have or quality tst.
For single word suggestions you can try a dictionary based service or software package.
Lets say I am calling a web api such as:
http://testapi.com/search?type=2
That would work fine for a single type, but what if I wanted type 1 and type 2. Is there a standard way to call this? I tried:
http://testapi.com/search?type=2|1
http://testapi.com/search?type=2&type=1
With no success..
Or is the only way typically to do this with web apis to make two calls and then combine the results yourself?
In case it helps - Specifically in this instance I believe the website developer has made the website and API via codeigniter.
So based on the comments it appears that there is no 'standard way'. If you need something like this you have two choices:
a. Place an enhancement request against the API for some custom syntax to allow OR (this is what I did and now use)
or
b. Right code to loop through each of the possibilities and union results.
When I search for "football images" on google.co.uk, it knows that I mean the sport that elsewhere might be called "soccer". If I do the same search on google.com, I get American Football.
I'm using the custom search API - how can I tell it that I'm in the UK and would like results relevant to here?
You can limit your engine to operate on sites from a particular country via "cr" param, e.g. in Custom Element it looks like this:
<gcse:search cr="gb"></gcse:search>
Google knows some synonyms on the web, but if your particular use case is not correctly recognized you can add it in Control Panel in Search Features > Synonyms
More on synonyms:
Sorry, I ended up answering this myself. I couldn't get any of the instructions under the custom search API itself to work (although the answer offered above was also mentioned there, but this just made my CSE Context XML apparently invalid), but you can make requests to a custom search engine by using the instructions here https://developers.google.com/custom-search/json-api/v1/using_rest and an API key.
This is how I did it;
<gcse:search cr="countryUK"></gcse:search>
You can even return results in a specific language, code shown below returns results only in french;
<gcse:search lr = "lang_fr"></gcse:search>
This is the reference for Google Custom Search Element Control API: https://developers.google.com/custom-search/docs/element?hl=en
Try to set the 'gl' parameter to the country you want.
For details, look into CSE:list
I am using Google's custom search API, I make an HTTP request to a URL that looks like this:
https://www.googleapis.com/customsearch/v1?key=<my-key>&cref=&num=10&q=how+can+i+do+htis
if you search for "how can i do htis" on Google you are told "Showing results for how can i do this", and give you some results (call them result set A)
but if you use the API to search for the misspelled string, you get different results than those of A... Searching with a correctly spelled string gives you result A, which matches the ordinary search service on Google
Is there a way to search directly using the suggested string? I want to use the API I can't afford implementing a spell checker myself that can also correct people names and everything
I think what you want to do is possible using the spelling suggestions of Google. This is part of the xml-results returned by your query.
See API here.
Is there a way to search and retrieve the results from On-Line Encyclopedia of Integer Sequences (http://oeis.org) programmatically?
I have searched their site and the results are always returned in html. They do not seem to provide an API but in the policy statement they say its acceptable to access the database programmatically. But how to do it without screen scraping?
Thanks a lot for your help.
The OEIS now provides several points of access, not just ones using their internal format. These seem largely undocumented, so here are all of the endpoints that I have found:
https://oeis.org/search?fmt=json&q=<sequenceTerm>&start=<itemToStartAt>
Returns a JSON formatted response of the results found from the sequenceTerm given. If too many results were returned, count will be > 0 whilst results will be null. If no results were returned, count will be 0. itemToStartAt is used for pagination of results, as only a maximum of 10 are ever returned. This starts at 0. If you wanted to return a second page of results, this would equal 10. Information about what each of the entries means can be found here.
https://oeis.org/search?fmt=text&q=<sequenceTerm>&start=<itemToStartAt>
Exactly the same arguments as before, however this returns it in the OEIS internal format. Which is largely written about here. Unless your project requires it, I'd highly recommend using the JSON format over this.
https://oeis.org/search?fmt=<json|text>&q=id:A<sequenceNumber>
Will return a single result if the sequenceNumber is found. This is the suggested method for obtaining single sequences, as it appears to be far more optimised than some of the alternative methods that can be used as queries. Requests often take under a second. Alternative search query methods can be found on this page.
https://oeis.org/A<sequenceNumber>/graph?png=1
This endpoint can be used to grab the images used to graph the data points. Alternatively, setting png to equal to zero returns the HTML page containing a graph of it.
https://oeis.org/recent.txt
This returns a list of recently updated entries in the OEIS internal format. There are no parameters available, or JSON format, as this seems like a static text file that is simply being served to the client. Due to the length of replies from the OEIS database (for some sequences replies can take above five seconds), I'd highly recommend heavily caching requests and using the above endpoint to update them when they change.
A URL of the form http://oeis.org/search?fmt=text&q=2,5,14,50,233 gives a nicely formatted text output.
But it seems there is no way to get a single sequence in text form.
If you happen to use Mathematica, it sounds like the following notebook might help. It allows you to specify a sequence and automatically import a detailed list of matching entries from the OEIS:
http://www.brotherstechnology.com/math/oeis_mathematica.html
It looks like direct use of their CGI program is the only API they provide.
URL for Searching the Database
https://oeis.org/search?q=id:A000032&fmt=text
gives the plain text form of an entry in their internal format
