Choosing between Elasticsearch and Solr

One of the questions we're asked all the time is which of the two most popular open source search engines is best for a particular use case - and the answer is always 'it depends'. Broadly speaking, Apache Lucene/Solr and Elasticsearch are very similar in terms of features and performance. If you've already chosen one of them, there's very few reasons to incur the inevitable extra work of switching to the other. However if you're still not sure which to choose, read on. Solr,...Continue reading

Helping Bloomberg build a real-time news search engine with Luwak

Searching for IP addresses in text with Elasticsearch

We recently implemented a search solution for a customer using Elasticsearch. Most of their requirements were fairly standard, however they also wanted to be able to search for IP addresses embedded in the document text, using a flexible and precise search syntax, e.g. given the following document fragment:

the following searches should all find the document:

The trouble with tabbing: editing rich text on the Web

Matt Pearce, who joined the Flax team earlier this year, writes: A recent client wished to convert documents to and from Microsoft Office formats, using a web form as an intermediate step for editing the content. The documents were read in, imported to a Solr search engine, and could then be searched over, cloned, edited and transformed in batches, before being exported to Office once more. The cont...Continue reading

Three reasons why your search may be prehistoric

ArnoldIT wondered today why we were bothering to announce an upgrade to the venerable dtSearch engine, when they "weren’t aware of too many people still using that software". Perhaps it's time for a quick reality check here - we regularly see clients with search engines that many would consider prehistoric still in active use. Here's some reasons why that might be so:
