Search & Filtering

The search bar filters what's visible in the sidebar. Type a query and series and files that don't match your pattern are hidden.

Most of the time you can type a word to find series by name, but the search system also supports boolean logic, wildcards, value-based filtering, and file-level queries.

Searching for Series

Simple Text Search

Type any text to filter series by name. Matching is case-insensitive and works as a substring match.

You type	What shows up
voltage	Any series with "voltage" in the name — Voltage_A, Bus_Voltage_1, etc.
freq	Frequency, Freq_Response, Low_Freq_Mode, etc.

A file stays visible as long as at least one of its series matches.

Exact Matching with Quotes

Wrap a term in double quotes to match the full series name exactly (still case-insensitive).

You type	Matches	Doesn't match
"Frequency"	Frequency	Frequency_Response, Low_Freq
"Active Power"	Active Power	Reactive Power, Active_Power_Output

Wildcards

• * matches any characters (including none)
• ? matches exactly one character

Pattern	Matches	Doesn't match
Volt*	Voltage, Volt_Drop, Volt	Line_Voltage
*Current*	Line_Current, Current_A	—
V?ltage	Voltage, Valtage	Vllltage

Combining with Boolean Operators

Operator	Syntax	Example
AND	space or &	voltage current or voltage & current
OR	|	voltage | current
NOT	!	!reactive
Grouping	< >	<voltage | current> & phase_a

Precedence: NOT > AND > OR

So voltage | current & !reactive is evaluated as voltage | (current & (!reactive)).

Use angle brackets to override precedence: <voltage | current> & phase_a means "series matching voltage OR current, that also contain phase_a".

Examples

Query	What it does
voltage	Series containing "voltage"
voltage | frequency	Series containing "voltage" or "frequency"
power & !reactive	Series with "power" but not "reactive"
<voltage | current> & phase_a	Voltage or current series, filtered to phase A

Filtering by Data Values

You can filter series based on their actual data values using a : after the column name. This is useful for finding series that exceed a threshold or fall within a range. At present this is a little complicated, and not very performant so there will be a new filtering feature added in a future update.

Basic Value Filters

Syntax: column_name:operator value

Operator	Meaning
:>	Greater than
:>=	Greater than or equal
:<	Less than
:<=	Less than or equal
:=	Equal to

Examples:

Query	Meaning
Voltage:>1	Series where any Voltage value exceeds 1
Freq*:<=50	Series starting with "Freq" where any value is at or below 50
*Power:>100	Series ending with "Power" where any value exceeds 100

The column name supports the same matching as regular search — no wildcards means exact-then-substring matching, wildcards use glob matching.

Filtering at a Specific Time

Add @time to check the value at a particular point in time:

Voltage:>1@5

This checks if Voltage is greater than 1 at time 5. If the exact timestamp doesn't exist, the nearest available point is used.

Filtering Across a Time Range

Add @start-end to check values within a time window:

Frequency:<49.5@0-10

This checks if Frequency drops below 49.5 at any point between time 0 and 10. Both ends of the range are inclusive.

Column Names with Spaces

Use quotes around the column name when it contains spaces or special characters:

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

How Value Filters Affect Visibility

Value filters work at the file level — if any series in a file satisfies the condition, the entire file is shown. This is different from text search, which filters individual series.

Mixed Queries (Value + Text)

You can combine value filters with text search in the same query. When you do, the two parts serve different purposes:

• Value filter decides which files to show
• Text search decides which series within those files to show

For example:

Voltage:>1 & Active Power

This means: show files where any Voltage value exceeds 1, then within those files only show series containing "Active Power".

Another example:

P_*:>100@5-10 frequency

Show files where any P_* series exceeds 100 between time 5 and 10, then within those files only show series containing "frequency".

Filtering by File Name

Use the file: prefix to filter at the file level instead of the series level:

file:case1*

This shows only files whose name matches case1*, and displays all series within those files. The matching supports wildcards and is case-insensitive, just like series search.

Query	What it shows
file:simulation	Files with "simulation" in the name
file:case1*	Files starting with "case1"
file:*.csv	Files ending with ".csv"

Quick Reference

Syntax	What it does	Example
term	Substring match (case-insensitive)	voltage
"term"	Exact full-name match	"Active Power"
*, ?	Wildcards	Volt*, V?lt
A B or A & B	AND	voltage current
A | B	OR	voltage | frequency
!A	NOT	!reactive
<A | B> & C	Grouping	<voltage | current> & phase_a
col:>val	Value greater than	Voltage:>1
col:>=val	Value greater or equal	Freq:>=50
col:<val	Value less than	Power:<100
col:<=val	Value less or equal	Current:<=5
col:=val	Value equals	Freq:=60
col:>val@t	Value at time point	Voltage:>1@5
col:<val@t1-t2	Value in time range	Freq:<49.5@0-10
"col name":>val	Quoted column name	"Active Power":>100
file:pattern	Filter by file name	file:case1*

Notes

• Simple queries (no special characters) are faster than advanced ones — just type and results appear instantly
• Invalid queries silently fall back: unrecognised syntax won't error, but the series won't match
• Time ranges are inclusive on both ends, and use the nearest available timestamp if an exact match doesn't exist
