Lucene library provides the core operations which are requireddish by any kind of kind of oceanrch application. Indexing and Searching.

How Search Application works?

Any oceanrch application does the few or all of the folloearng operations.

Step Title Description
1

Acquire Raw Content

First step of any kind of kind of oceanrch application is to collect the target contents on which oceanrch are to be conducted.
2

Build the document

Next step is to construct the document(s) from the raw contents which oceanrch application can belowstands and
interpret easily.
3

Analyze the document

Before indexing process to start, the document is to be analyzed as which part of the text is a candidate to be indexed. This process is calimmediateed analyzing the document.
4

Indexing the document

Once documents are built and analyzed, next step is to index all of them so thead wear this particular particular document can be retrived based on specific keys instead of whole contents of the document. Indexing process is similar to indexes in the end of a book where common words are shown with their own particular page numbers so thead wear these words can be tracked fastly instead of oceanrching the comppermite book.
5

User Interface for Search

Once a database of indexes is ready then application can make any kind of kind of oceanrch. To facilitate user to make a oceanrch, application must provide a user a mean or u0ser interface where a user can enter text and start the oceanrch process.
6

Build Query

Once user made a request to oceanrch a text, application need to prepare a Query object uperform thead wear text which can be used to inquire index database to get the relevant details.
7

Search Query

Uperform query object, index database is then checked to get the relevant details and the content documents.
8

Render Results

Once result is received the application need to figure out generally there how to show the results to the user uperform User Interface. How a lot information is to be shown at 1st look and so on.

Apart from these basic operations, oceanrch application can furthermore provide administration user interface providing administrators of the application to manage the level of oceanrch based on the user profiles. Analytics of oceanrch result is one more imslotant and advanced aspect of any kind of kind of oceanrch application.

Lucene's role in oceanrch application

Lucene plays role in steps 2 to step 7 mentioned above and provides clbumes to do the requireddish operations. In nutshell, lucene works as a heart of any kind of kind of oceanrch application and provides the vital operations pertaining to indexing and oceanrching. Acquiring contents and displaying the results is left for the application part to handle. Let's start with 1st basic oceanrch application uperform lucene oceanrch library in next chapter.
