Advanced Content Search

Powerful engine equipped to "grow up" and "be found"

Neighborhood search such as position consideration search and Boolean expression search are also available, which is known as the most powerful Japanese search engine. Function pages, such as search results, that used to generate and analyze statistical results in order to easily match search content requested by visitors, are also provided.

Since there is learning software, searched content will be corrected with time. Moreover, searched keywords can be stored according to user properties, each of the searched keywords can be separately distributed. For instance, a female visitor that used cosmetic products as her search keyword. Essential content will be displayed and controlled.

In the case where information could not be found by site visitors, in-site search will be used. However, if essential information is not available, the site may provide mismatched information. The search engine installed in HeartCore does not only avoid search result mismatching, it also benefits from raising the search efficiency, upgrading usability, and increasing conversion at the same time.

convenient scoring feature

Access ranking

In the sequence of search results, the order of consideration of the number of accesses of each record is enabled.

Access ranking

Value keywords in specific fields

- Add priority levels from 1(lowest) to 5(highest) for fields
- Tune rankings for fields

For example, the product database has columns named "title" and "details". Product A contains a word “低燃費” once in the title field and twice in the details field, while Product B does not contain the word “低燃費” in the title field and happens to contain it five times in the details field.

Specific field keyword featured

When users search for “低燃費”, Product A is most likely the one they are looking for. With the QuickSolution standard ranking method, however, Product B will be ranked higher than Product A as the keyword appears more frequent in Product B.

Adding priority to the specific fields, it will be considered more relevant that the keywords appear in the fields specified.
