What Does the Status of a Document Mean?

Use

The queue server has a status for each document in a queue. The status allows you to track the processing of documents.

The graphic below gives an overview of the statuses that a document can have.

The statuses mean the following:

Status	Purpose
`Delayed...`	The document is not yet processed. There is a new, updated version of a document that is currently being processed. As long as the previous version has not yet been completely processed, the new version is shown as being 'delayed'.
`To Be Preprocessed`	The document is about to be preprocessed.
`Preprocessing`	The document is being preprocessed. The preprocessor carries out the following steps: Resolving the URI This step is necessary if the preprocessor only received the document in the form of a URI. The preprocessor loads the document from the storage location referenced by the URI. Filtering The preprocessor extracts the text content and converts it to Unicode format UTF-8. Linguistic analysis (normalization, root reduction, tokenization)
`Preprocessing Failed`	The document could not be preprocessed. This might be because the URI of the document could not be reached or because the document contains no readable text.
`To Be Indexed`	The document is about to be indexed.
`Indexing`	The document is being transmitted to an index server and indexed there.
`Indexing Failed`	The document could not be transmitted to the index server and, as a consequence, could not be indexed.
`To Be Optimized`	The document is waiting on the index server to be optimized.
`Optimizing`	The document is being optimized.
`Optimization Failed`	The document could not be optimized.
`OK`	The document has been processed successfully. If it was added to the index, it can now be found using the index.
