Sometimes, simple search isn’t good enough. When that happens, it’s time for super search.
Simple Attribute Searches
Attribute searches are helpful when you’re looking for things with particular properties. For parts, every attribute in the part is indexed, so it’s generally a good idea to pick common attribute names (e.g., height, resistance, package). Attribute names are case-insensitive.
If you’re looking for multiple values, you can join them with OR, parenthesizing the values. If either the attribute or the value has spaces, you’ll need to double-quote them.
-
tags:usb
- Search for projects and parts tagged with usb.
-
owner:upverter
- Search for projects owned by upverter.
-
package:(0402 OR 0603)
- Search for parts with a package of 0402 or a package of 0603.
-
manufacturer:"Texas Instruments"
- Search for parts manufactured by Texas Instruments.
Numeric Queries
Thanks to lots of unit tests, searching for specific number values is relatively painless. Units are normalized (e.g., m, meter, metre; A, Amps, Amperes; ° Celsius, ° C, degrees C) and SI prefixes are expanded. In other words, 3cm is equivalent to 30mm, both in Upverter search and in reality. (We’re also not picky about the space between the number and the units, so you can even write 30 mm, if you really wanted to.)
-
resistance:330ohms
- Search for all parts with a resistance attribute of 330ohms. Equivalent to resistance:“330 ohms”, resistance:330Ω, resistance:0.33kohms, resistance:“0.33 kΩ”, and other such variants.
The difference between resistance:330 (without units) and resistance:330ohms (with units) is subtle, and probably not relevant for most searches. An attribute value with units will be indexed as both with and without units; an attribute value without units will only get indexed as a number, and shows up only in the unitless search.
In other words, when you create a part, don’t forget your units!
Range Queries
Upverter search now allows you to search for a property within a particular range. Whee!
-
resistance:[300ohms TO 400ohms]
- Search for all parts with a resistance property of 300 ohms to 400 ohms, inclusive on both sides. Note that number normalization is in play here, so 300ohms is equivalent to 0.3kohm and so on. Also note that due to how we’re handling units (that is, not at all), searching resistance:[300ohms TO 400ohms] is equivalent to resistance:[300 TO 400], which is equivalent to resistance:[300F TO 400F]. (If you can think of a plausible situation in which this gets weird, let me know.)
-
resistance:{330ohms TO 400ohms]
- Search for all parts with a resistance property of 330 ohms to 400 ohms, exclusive on the lower end but inclusive on the higher end.
