Solr search t-shirt returns shirt

Asked 2022-Jan-30 at 10:04

When i'm searching for t-shirts on my solr, it returns shirts first. I configured my field as follows:

...

ANSWER

Answered 2022-Jan-23 at 14:56

Here you are using the StandardTokenizerFactory for your field which is creating a token as shirt and hence a match.

StandardTokenizerFactory :- It tokenizes on whitespace, as well as strips characters

The Documentation for StandardTokenizerFactory mentions as :-

Splits words at punctuation characters, removing punctuations. However, a dot that's not followed by whitespace is considered part of a token. Splits words at hyphens, unless there's a number in the token. In that case, the whole token is interpreted as a product number and is not split. Recognizes email addresses and Internet hostnames as one token.

If you want to perform search on the "t-shirt", then it should be tokenized. I would suggest you to use the KeywordTokenizerFactory

Keyword Tokenizer does not split the input provided to it. It does not do any processing on the string, and the entire string is treated as a single token. This doesn't actually do any tokenization. It returns the original text as one term.

This KeywordTokenizerFactory is used for sorting or faceting requirements, where one want to perform the exact match. Its helpful in faceting and sorting.

You can have another field and apply KeywordTokenizerFactory to it and perform your search on it.

Upgrade Apache Solr 8.10.1 log4j 2.14.1 version to 2.15 to address critical vulnerability

Asked 2022-Jan-19 at 09:31

Recently a critical log4j vulnerability was discovered.

I want to upgrade the log4j as used by my current Solr instance, so I checked here. However, I don't see a log4j.properties file in "/server/resources/" folder. All I see there is:

jetty-logging.properties
log4j2.xml
log4j2-console.xml

None of these files contain a version. So to upgrade, is it safe to download the latest version of log4j and overwrite the existing jars in folder "\solr-8.10.1\server\lib\ext", or what are the recommended steps to upgrade?

...

ANSWER

Answered 2021-Dec-13 at 15:51

The link you're pointing to is for an older version of Solr (6.6 instead of 8.10.1). The correct version is https://solr.apache.org/guide/8_10/configuring-logging.html where it mentions using log4j 2.

The file log4j2.xml (and even `log4j.properties for that matter) configure the logging itself, not the version of log4j. So updating that file is irrelevant.

Here's what the project page recommends:

2021-12-10, Apache Solr affected by Apache Log4J CVE-2021-44228

...

Description: Apache Solr releases prior to 8.11.1 were using a bundled version of the Apache Log4J library vulnerable to RCE. For full impact and additional detail consult the Log4J security page.

...

Mitigation: Any of the following are enough to prevent this vulnerability for Solr servers:

Upgrade to Solr 8.11.1 or greater (when available), which will include an updated version of the log4j2 dependency.

Manually update the version of log4j2 on your runtime classpath and restart your Solr application.

(Linux/MacOS) Edit your solr.in.sh file to include: SOLR_OPTS="$SOLR_OPTS -Dlog4j2.formatMsgNoLookups=true"

(Windows) Edit your solr.in.cmd file to include: set SOLR_OPTS=%SOLR_OPTS% -Dlog4j2.formatMsgNoLookups=true

Follow any of the other mitgations listed at https://logging.apache.org/log4j/2.x/security.html

What you're proposing (overwrite the existing jars in folder "\solr-8.10.1\server\lib\ext") seems like the second approach, so it should probably work fine. Just make sure this is the correct place that contains the log4j dependency.

Solr - Boost result with exact match in the begginning of term

Asked 2021-Oct-21 at 20:14

For an e-commerce store I have two products like these indexed in Solr

easyCover Silicone Protection Cover for Canon EOS 80D (Camouflage)
Canon EOS 80D DSLR Camera with 18-135mm Lens

Now, for a search query "Canon EOS 80D", I am getting product ranked as 1,2 as a result.

How can I rank Product 2, which is "Canon EOS 80D DSLR Camera with 18-135mm Lens" rank first?

Basically, I want to give more boost/weight-age to the product that has term in the beginning of the name phrase compared to those product that has same term not the first in the name phrase.

Pls advise.

...

ANSWER

Answered 2021-Oct-21 at 20:14

I strongly advice not to use the token positions to boost your product over accessories. Imagine a customer is searching for "EOS 80D" - he will still get the silicone cover on first position.

A better solution would be to boost on a secondary field. Some ideas:

put a boost function on the price, as the main products usually have higher prices as the accessories e.g bf=log(price)
use a field to categorize your items in products and accessories - and put a boost on this, e.g. bq=category:product
create a field to list the products that an assessory can be used with. This will also help you to advertise the accessories in future. But it will now also help to find the main products, by boosting the the documents that don't contain references here.

I know that this answer is not a direct solution for the original question - but sometimes there are much simpler solutions for a problem if you look at it from a distance.
