No, streaming expressions don't flow through the regular document output process and don't support DocTransformers. Best, Erick On Sun, Mar 26, 2017 at 9:03 AM, adfel70 wrote: > Hi > does streaming expressions support doc transformers? > To be more specific, I have a nested docs data model. > I

RE: Index scanned documents

While building directly into Solr might be appealing, I would argue that it is best to use OCR software first, outside of SOLR, to convert the PDF into "searchable" PDF format. That way when the document is retrieved, it is a lot more useful to the searcher - making it easy to find the text with

Hi John. thanks for that. That's actually a good option but I would need the category text on the field so I can facet on the field and get every category and the number. On 26 March 2017 at 18:27, John Blythe wrote: > You could use keepwords to filter out any other words besides your bag and >

Re: Multi word synonyms

I use the keyword tokenizer and then pattern replace to transform multi words into underscore connected tokens. For instance, "Burger Joint" transforms to "burger_joint" which then looks in my synonym filter for underscored synonyms. When it matches I then replace underscores with spaces or just to

Re: Classify document using bag of words

You could use keepwords to filter out any other words besides your bag and then have a synonym filter that translates the remaining word(s) to a corresponding category/classification On Sun, Mar 26, 2017 at 12:05 PM marotosg wrote: > Hi, > > I have a very simple use case where I would need to cl

Classify document using bag of words

Hi, I have a very simple use case where I would need to classify a document using a bag of words. Basically if a field within the document contains any of the words on my bag then I use a new field to assign a category to the document. Is this something achievable on Solr? I was thinking on usin

Multi word synonyms

Hello, Does anyone have a good solution for working with multi word synonyms? I've been reading a lot about this online and haven't really found a great solution to it. I use the SynonymFilterFactory at index time, but words don't really get matched to the appropriate multi word synonyms, even tho

Re: Index scanned documents

Hi Walled, I've never done that with solr, but you would probably need to use some OCR preprocessing before indexing. The most popular library I know for the job is tesseract-orc . If you want to do that inside solr I've found that Tika has some support for that
