File Search

A simple java application that can search for terms in all the files in a given directory

Instructions to run the code

• Compile the all the java files in the src folder.Java version used is 1.8.
• Now run the command java -cp . com.company.FileSearchProject.App <path_to_directory>
• The above command will run the program with the path to the directory as given
• There are already 11 files present in the directory "FileSearchProject\src\main\resources" for ease.
• The user can then enter the search term once the search> appears in the command prompt
• The program searches for the presence of the words seperately and as a whole
• The First search is done on the words individually.
• Once Individual words are found seperately, the search now happens for the search term as a whole automatically.
• If the whole term is found, then the rank "100%" is shown against the file name.
• If the whole term is not found, then appropriate rank is shown.
• The formulae used for calculating rank is as given:
  • Weightage is distributed among the individual words and the whole term.
  • So if the search term contains 4 words, then weightage is distributed among the four words and the whole term equally. The weightage is calculated by 100/(no.of.words + 1). So for the given example of 4 words, the individual weightage would be 100/5 = 20 among the 4 words and 20 for the whole term.

Example:

      search term = "Aelius Maximus Decimus Meridius"
      So the weightage individually would be 100/(4+1) = 20
	If just "Aelius" is found:
		then the rank is 20%
	If "Aelius" and "Maximus" is found:
		then the rank is 50%
	If all the words "Aelius","Maximus","Decimus","Meridius" are found,
	but not as a whole
		then the rank is 75%
	If the term "Aelius Maximus Decimus Meridius" is found as a whole
		then the rank is 100%

Few assumptions :

	* The search is case insensitive
	* Input handling is not done to handle all the cases(wildcards)
	* The directory to be searched must only contain files and not directories.
	* A break statement is to be added in the while(true){} loop when running testcases
	  else the test cases wont stop their execution.
