Choosing well
Check phone access
If staff need search on a Xiaomi, Redmi or POCO phone, verify that the product provides an Android app or a mobile-friendly web experience. Moveworks lists Android and iOS support alongside web access.
A web platform can work across devices, while a self-hosted or desktop-focused deployment may need a separate mobile plan.
Review connectors and permissions
Data connectors determine which business systems can feed the search index. Check the connector list against the services your team uses.
Permission sync matters when search results must follow existing access rules. Confirm how the product handles permissions before indexing company content.
Match the deployment model
Deployment options shown here span web, API, Linux, self-hosted, Windows and macOS. Choose a hosted setup when you want less infrastructure work, or a self-hosted option when your team manages Linux systems and deployment.
Compare free and paid paths
Apache Solr, Datafari, Elasticsearch, Fess, Google Search Console and GoSearch Analytics each show a free plan. Elasticsearch shows a $99-per-month starting service and a 14-day trial; GoSearch Analytics starts at $20 per user monthly.
Paid products such as Coveo, Glean Agent Builder, Guru and Moveworks may require pricing details from the vendor. Mindbreeze InSpire shows a free trial without a free plan.
Check language and API needs
Indexed-language coverage affects search across multilingual content, so compare the languages stated for a product with your documents.
API access can connect search to internal tools and workflows. Check whether the API fits your integration plan and whether open-source code is available when you need to inspect or adapt it.
