Visited Date Sort Threshold

Concept: Visit Date Sort Threshold

Purpose

The visitedDateSortThreshold concept refines search result relevance by re-sorting notes with similar match scores based on their last visited date (Note.visited). This ensures that recently visited notes are prioritized within groups of closely matched results.

Key Idea

• Threshold-Based Grouping: Search results are grouped if their match scores fall within a defined similarity threshold. This allows grouping notes with nearly identical relevance scores.

• Visited Date Sorting: Within each group of similar scores, notes are further sorted by their last visited date, ensuring that the most recently viewed notes appear higher in the results.

Use Case

This concept is valuable when dealing with search results that have close match scores.

Example

Consider a scenario where 4 notes have the following match scores and visit dates:

• Note A: Score = 2.0, visited on = 2023-09-01
• Note B: Score = 0.9, visited on = 2023-09-02
• Note C: Score = 0.95, visited on = 2023-09-03
• Note D: Score = 0.5, visited on = 2023-09-04

Let's say we have visitedDateSortThreshold set to 0.1. Therefore, notes with match scores within 0.1 difference are eligible for re-sorting based on visit date.

In this example, the search response will be:

1. Note A (least recent visit but highest match score)
2. Note C (most recent visit out of B, C)
3. Note B
4. Note D (most recent visit but low match score)
