METHOD AND DEVICE FOR MANAGING INDEX
Embodiments of the present disclosure provide a method and device for managing index. For example, there is provided a method, comprising: obtaining a first index term in a first index, the first index term corresponding to a first index content in the first index, the first index content indicating a position of the first index term in a document; generating a reading of the first index term; and adding the reading as a second index term into a second index, the reading corresponding to a second index content indicating the first index term. Corresponding device and computer program product are also provided.
1 . A method for managing index, comprising:
obtaining a first index term in a first index, the first index term corresponding to a first index content in the first index, the first index content indicating a position of the first index term in a document;
generating a reading of the first index term; and
adding the reading as a second index term into a second index, the reading corresponding to a second index content indicating the first index term.
2 . The method according to claim 1 , wherein the adding the reading as a second index term into a second index comprises:
in response to the reading matching an existing index term in the second index, appending the second index content indicating the first index term to the existing index term.
3 . The method according to claim 1 , wherein the adding the reading as a second index term into a second index comprises:
in response to the reading mismatching all existing index terms in the second index, creating the second index term and the second index content.
4 . The method according to claim 1 , wherein the second index excludes field information of the document.
5 . The method according to claim 1 , further comprising:
in response to a predefined condition related to the number of operations on the document being satisfied, re-creating the second index.
6 . The method according to claim 1 , further comprising:
generating a reading for a received query term;
in response to the reading of the query term matching a third index term in the second index, generating an expanded query term based on an index content corresponding to the third index term; and
performing a query on the first index by using the expanded query term.
7 . An electronic device, comprising:
at least one processing unit; and
at least one memory coupled to the at least one processing unit and storing machine-executable instructions, the instructions, when executed by the at least one processing unit, performing acts including:
obtaining a first index term in a first index, the first index term corresponding to a first index content in the first index, the first index content indicating a position of the first index term in a document;
generating a reading of the first index term; and
adding the reading as a second index term into a second index, the reading corresponding to a second index content indicating the first index term.
8 . The device of claim 7 , wherein the adding the reading as a second index term into a second index comprises:
in response to the reading matching an existing index term in the second index, appending the second index content indicating the first index term to the existing index term.
9 . The device of claim 7 , wherein the adding the reading as a second index term into a second index comprises:
in response to the reading mismatching all existing index terms in the second index, creating the second index term and the second index content.
10 . The device of claim 7 , wherein the second index excludes field information of the document.
11 . The device of claim 7 , wherein the acts further include:
in response to a predefined condition related to the number of operations on the document being satisfied, re-creating the second index.
12 . The device of claim 7 , wherein the acts further include:
generating a reading for a received query term;
in response to the reading of the query term matching a third index term in the second index, generating an expanded query term based on an index content corresponding to the third index term; and
performing a query on the first index by using the expanded query term.
13 . A computer program product for managing an index, the computer program product comprising:
a non-transitory computer readable medium encoded with computer-executable program code for managing the index, wherein the code is configured to enable the execution of:
obtaining a first index term in a first index, the first index term corresponding to a first index content in the first index, the first index content indicating a position of the first index term in a document;
generating a reading of the first index term; and
adding the reading as a second index term into a second index, the reading corresponding to a second index content indicating the first index term.
14 . The computer program product according to claim 13 , wherein the adding the reading as a second index term into a second index comprises:
in response to the reading matching an existing index term in the second index, appending the second index content indicating the first index term to the existing index term.
15 . The computer program product according to claim 13 , wherein the adding the reading as a second index term into a second index comprises:
in response to the reading mismatching all existing index terms in the second index, creating the second index term and the second index content.
16 . The computer program product according to claim 13 , wherein the second index excludes field information of the document.
17 . The computer program product according to claim 13 , wherein the code is further configured to enable the execution of:
in response to a predefined condition related to the number of operations on the document being satisfied, re-creating the second index.
18 . The computer program product according to claim 13 , wherein the code is further configured to enable the execution of:
generating a reading for a received query term;
in response to the reading of the query term matching a third index term in the second index, generating an expanded query term based on an index content corresponding to the third index term; and
performing a query on the first index by using the expanded query term.
