Ask HN: Where are the good search engines for mathematical formulas?
A Hacker News user asks the community for recommendations on effective search engines for mathematical formulas, highlighting the current frustration with existing tools. The author notes that many options are either offline, provide irrelevant results, or are abandoned projects. This post resonates with the HN audience, who often grapple with specialized search challenges and appreciate practical solutions to technical problems.
The Lowdown
An "Ask HN" post initiates a search for reliable search engines specifically designed for mathematical formulas. The author expresses a significant challenge in finding a functional and accurate tool for this purpose.
The core issues identified by the author include:
- approach0.xyz: This service is noted as being offline, rendering it unusable.
- searchonmath.com: This engine is criticized for delivering irrelevant results, illustrated by searching for
F = m aand receivingp = m v. - search.mathweb.org: This site appears to be a collection of abandoned projects and offline resources, indicating a lack of ongoing maintenance or utility.
The author's query underscores a clear gap in effective search capabilities for mathematical expressions within the current online landscape.
