hi guys , i need an algorithm which i can implement for searching. the question is: an item has thousands of urls and keywords. (say, item = url + keywords) now, when i want to look for a particular item, i have to do a full text search and retrieve the item. the problem is when the no. of items are increasing, what is want is: kindof an encryption algorithm.(not sure if this is appropriate). when the user searches for something, say for 'X' keyword, i dont want to lookup the DB / do a full text search. i want the results to be stored in the 'X' keyword itself. ; so, X theoritically holds the results (or atleast the top 10, 20 of them). so, X is encrypted key and this needs to be decrypted at the client. feel free to pm me , if you have the right skills and caliber no budget constraints... thanks tom

Hi, professional Delphi developer here. I already have experience with various search lists and optimizations, for example, one of the projects would be this one: https://www.freelancer.com/projects/Delphi-Algorithm/Optimize-simple-string-search-component.html Can I get more details about what kind of search you need? From the description, it's very difficult to understand what you want to achieve. I guess it would be best to build binary-tree based search, but I would need clearer description first, ideally with example. My hourly rate is 50$, but I tend to deliver fast and high quality work. I am also available for communication over mail or Skype during and after the project completion for any possible issues. Please contact me back if interested. Thanks, Marko Paunovic

I am very proficient in c, c++. I have 15 years c++ developing experience now, and I have worked for 5 years. My work is online game developing, and mainly focus on server side, the lauguage is c++ under linux os. So, programming in c++ is never a problem. I used c++ to make many great projects, for example, I made the tools which can convert java files to c++ with the same meaning, ofcourse garbage collection included. I made our own mobile game using c++, I even can show you the demo of client. Trust me, please let expert help you.

Hello! I am proficient in C/C++ and I am interested in your project. What you are looking for is a sort of a map. It is a container that holds items of type key|value and organizes them by the keys. Therefore, for every item your refer to the project description, you would create n items of type keyword|url, where n is the number of keywords for the item url. So this is going to work like this: 1. Create the map for your items (url + keywords) 2. When a user makes a search containing several keywords, you retrieve all the urls that correspond to each keyword. The map is optimized so this is done very fast. 3. (optional) Make a set for the urls of each keyword. Create all the possible intersections of those sets and order the urls accordingly. This is to create a sort of "relevance" metric and grade the urls. 4. Present the results to the user. Alex

I have few questions as 1) You have mentioned language as C++ programing and Java. Basically in which language you want the application to be developed? 2) Requirement is not fully provided, so i would like to know the kind of keyword and items you are using for searching. Thank you very much!

Hi, I noticed that your description is very ambiguous, so if you what that a result be stored in X for example, the app must do a search ( DB, file text whatever ) in order to have something to store in X. I think is more appropiate this solution : you have a app that receive as input the keyword for you are looking at, the app parse the file or interogate the DB. The app gerenate a file encrypted using a private key, and for decription I can made another app that decrypts data. Regards, Ionut

Hello, I have read your problem statement and I think i have a solution, Firstly, I will work to build the encryption/decryption process, the encryption key will be public so it can be used by the item originator. When the user searches for a particular text the system will encrypt this and run the resulting sequence search on the string you refer to as 'item' if found/ not found the user is alerted Point of Information: If we are searching encrypted text using pattern matching, that is search for sh returns she, ship,sheep etc if would be prudent to separate the values in the encrypted string 'item' using some sort of character to allow the full encrypted string to be retrieved Is this what you have in mind, if so I would love to hear from you
