I have worked with india enterprise search for few years now both at customer level & vendor side (Vendor : HCL). We were handling large volumes or files everyday so need an ETL tool that can perform quick turnaround time without affecting our business needs / workflow process flow/etc., India Enteprise is best fit into such scenario where we needed it most because they offer turn key solution right outoff box - no config required other than some initial guidance about your workloads if any are different form ours by nature! No major downtime while doing set up phase itself either!! Very friendly team who guide you through during implementation life cycle stage! They also do extensive training sessions after signing NDA agreement between clients& vendors!! If anything goes wrong just call them immediately instead going thru legal route first only when things go bad then will escalate this matter I love how easy it is for me to use this product with my team members who are not tech savvy at all! This has made our job so much easier when searching through documents or emails that need attention. Nothing really bad about using india enterprise search but if you're looking into something more robust then maybe look elsewhere? We have been able solve many problems by just typing them out within IndiaEES (as we call it).
