php - Script to find if a similar question exists -


G'day,

I am creating a frequently asked question system, and users Should be able to see if a similar question is asked. Just wondering if anyone is aware of a script (preferably PHP, or Javascript, or possibly an action), which any kind of A would do?

Thank you.

I think the best You can hope for a simple search engine: split words into question and record words against the question table question (question_id, word)

Then a question like a new question To get a

table query (id, text, ....)

ID $ x with question: 

  SELECT prev.id , Questions with common questions as prev.text, count (*) , Prev_words words, curr_words where curr_words.question_id = $ x and curr_words words = prev_words.word and prev_words.question_id = prev.id group ID, COUNT (*) Text command Diissi limit .....?

You can definitely implement more detailed methods on returning shortlists - but this will definitely be the first step.

c.

'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
