Method and apparatus for data search, system, device and computer readable storage medium

A data search method, comprising:

• determining semantic-understanding information corresponding to a received search term by subjecting the search term to semantic understanding;
• analyzing the semantic-understanding information to obtain timeliness requirement information of the search term;
• determining an acquisition mode of resource result corresponding to the search term based on the timeliness requirement information of the search term;
• and
• obtaining the resource result corresponding to the search term by using the determined acquisition mode,
• wherein the acquisition mode of resource result comprises a mode of retrieving an existing resource result from a preset cache and a mode of triggering penetration of the preset cache to obtain an updated resource result from a back end,
• wherein the step of analyzing the semantic-understanding information to obtain the timeliness requirement information of the search term comprises:
• calculating the timeliness requirement information of the search term according to an information item in the semantic-understanding information and a preset weight coefficient corresponding to the information item in the semantic-understanding information, wherein the semantic-understanding information comprises at least one of the following information items:
• literal meaning, semantic integrity and probability of burst keyword, and
• wherein the step of determining the acquisition mode of resource result corresponding to the search term based on the timeliness requirement information of the search term comprises:
• determining, when a calculated value of the timeliness requirement information of the search term is greater than or equal to a preset first score, that the acquisition mode of resource result corresponding to the search term is the mode of triggering penetration of the preset cache to obtain the updated resource result from the back end, and
• determining, when the calculated value of the timeliness requirement information of the search term is less than the preset first score, that the acquisition mode of resource result corresponding to the search term is the mode of retrieving the existing resource result from the preset cache.
