The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Complex queries using double quotes

Asked by Gyftus in MySQL Server

Tags: , ,

Hello All

I am trying to figure out how create/provide a mechanism where my user can use double quotes to define which part of his/her queries will match exactly and which are not. The reason I am asking in this forums is because the only part that is consistent is the MySql db, the language is irrelevant. Answers can be given in pseudo code, or in any of the following java, php

Assume that I have a table with one field called 'description' and the table is called 'items' for the example sake. Also I have a form with a single text box which will be used to query this table.

The following inputs will result -> in the following queries

"aaaa" -> Will search for an EXACT match of the word "aaaa" in the description
"aaaa" bbb -> Will search for an EXACT match of "aaaa" AND any match of %bbb%
"aaaa bbbb" ccc-> Will search for an EXACT match of "aaaa bbbb" AND any match of ccc
"aaaa" "bbbb" -> Will serach for and EXACT match of "aaaa" OR "bbbb"

So forth and so on, you catch my drift in that the combination are inumerable, and I can't think of every thing the user is going to type, nor I want to restrict them. At the moment I am asking only about double quotes, but how about +,-,? ~ characters in the query

Anyways I am looking for an optimum way to do this, that is why I am giving 500 points. Please don't provide answers where I have to code each case, because I have 5 such fields in the form. Note- I will ask follow up questions
