Indexing

Indexing is the procedure which takes place before the documents become
available for searching. All the file contents must be pre-processed by the
chemistry component with the aim to extract all the chemical information from
them. Free-text indexing needs the same pre-processing phase as well.

The goal of this phase is to make the users' queries fast.

The indexing section of the menu contains four screens:

• Content sources - content
  sources are ChemLocator's terminology for locations where documents are found
  in. These can be cloud drive locations, local folders, etc.
• Cloud credentials - in the case
  of cloud-based content sources, credentials will need to be provided. These
  allow ChemLocator to be able to read the documents in your cloud storage
  location.
• Processing status - shows the
  status of any ongoing crawling and indexing.
• Index reset - allows the
  ChemLocator databases (both PostgreSQL as well as Elasticsearch) to be cleared
  and reset to a pristine state.
