Variables | |
const int | DB_CREATE_OR_OPEN = 1 |
Open for read/write; create if no db exists. | |
const int | DB_CREATE = 2 |
Create a new database; fail if db exists. | |
const int | DB_CREATE_OR_OVERWRITE = 3 |
Overwrite existing db; create if none exists. | |
const int | DB_OPEN = 4 |
Open for read/write; fail if no db exists. | |
const valueno | BAD_VALUENO = static_cast<valueno>(-1) |
Reserved value to indicate "no valueno". |
|
A count of documents. This is used to hold values such as the number of documents in a database and the frequency of a term in the database. |
|
A signed difference between two counts of documents. This is used by the Xapian classes which are STL containers of documents for "difference_type". |
|
A unique identifier for a document. Docid 0 is invalid, providing an "out of range" value which can be used to mean "not a valid document". |
|
A normalised document length. The normalised document length is the document length divided by the average document length in the database. |
|
The percentage score for a document in an MSet.
|
|
A counts of terms. This is used to hold values such as the Within Document Frequency (wdf). |
|
A signed difference between two counts of terms. This is used by the Xapian classes which are STL containers of terms for "difference_type". |
|
A term position within a document or query.
|
|
A signed difference between two term positions. This is used by the Xapian classes which are STL containers of positions for "difference_type". |
|
A timeout value in microseconds. There are 1 million microseconds in a second, so for example, to set a timeout of 5 seconds use 5000000. |
|
The number for a value slot in a document. Any value slot number except Xapian::BAD_VALUENO is valid. |
|
A signed difference between two value slot numbers. This is used by the Xapian classes which are STL containers of values for "difference_type". |
|
The weight of a document or term.
