Search Function Overview

The search function provides advanced filtering for both files and time-series data.
It supports Boolean logic, wildcards, and time-based filtering.

Search Behavior

  • File-Level Filtering → e.g. Voltage:>1 shows/hides entire files if any series matches.
  • Series-Level Filtering → e.g. Frequency shows only matching series.
  • Mixed Queries → e.g. Voltage:>1 & Active Power → select files where Voltage > 1, then show Active Power series.

Query Syntax

Text Search

  • Frequency → match series containing "Frequency"
  • "Exact Match" → exact phrase (case-sensitive)
  • file:pattern → match files by name (supports wildcards)

Boolean Operators

  • Voltage | Current → OR
  • Voltage & Current (or space) → AND
  • !Reactive → NOT
  • <...> → Grouping

Precedence: NOT > AND > OR

Wildcards

  • * → any chars (Volt* → "Voltage", "VoltDrop")
  • ? → one char (Curr?nt → "Current")

Time-Series Filtering

Column Matching

  • Voltage:>1 → exact/substring match
  • Volt*:>1 → starts with
  • *Power:>100 → ends with

Operators

  • :>, :>=, :<, :<=, :=

Time Ranges

  • Voltage:>1@5 → at time 5
  • Frequency:<49.5@0-10 → between time 0–10

Quoted Names

  • "Active Power":>100
  • 'Reactive Power':<=50

Examples

  • Frequency → match "Frequency"
  • Voltage | Frequency → Voltage OR Frequency
  • Power & !Reactive → Power but not Reactive
  • Voltage:>1 & Active Power → Voltage > 1, then show Active Power
  • P_*:>100@5-10 → P_* > 100 between times 5–10

Quick Reference Cheatsheet

Syntax Meaning Example
file:pattern Match files by name (wildcards ok) file:case1*
Term Match series containing term Frequency
"Exact Match" Case-sensitive exact phrase "Active Power"
A & B AND Voltage & Current
A | B OR Voltage | Frequency
!A NOT !Reactive
<A | B> & C Grouping with precedence <Voltage | Frequency> & Power
Col:>1 Greater than Voltage:>1
Col:<=100 Less than or equal "Active Power":<=100
Col:=50 Equal Freq:=50
Col:>1@t At specific time Voltage:>1@5
Col:<10@t1-t2 Across time range Frequency:<49.5@0-10
*, ? Wildcards Volt*, Curr?nt

Notes

  • Wildcards are case-sensitive
  • Time ranges are inclusive, nearest timestamp used if exact not found
  • Invalid queries fall back to text search
