I am doing a project on online Job application and need to implement a parser such that when someone enters some keywords for the search, it search for the keywords in the database and returns the results. I don't know how to do that. I have read some stuffs on parser but am really lost, is this the way that parser works!!
Some help will be really appreciated. Some examples whatever to understand what parser is and what it does and how to implement it plz.:mad:

You don't need a parser - you need a search engine. Simple database query for the keyword would look like:

SELECT * FROM job_apps WHERE keywords LIKE '%keyword1%' or '%keyword2%'

assuming that you store your job applications in job_apps table and keywords for each job applications are stored in keywords column.

You could also use the "MATCH" keyword to give you matches against full-text indexes in a database.
