This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing a fatal error on your shop page while searching, which results in a PHP error related to 'Call to a member function get_id() on bool', this might be due to an issue in the WooCommerce Multilingual plugin.
Solution:
We recommend you try the following steps after ensuring you have a full site backup:

1) Navigate to the 

wp-content\plugins--woocommerce-multilingual\inc

folder.
2) Open the 

class-wcml-comments.php

file for editing.
3) Scroll down to line 109.
4) Replace the existing code block with the following updated code:

From

foreach ( $translations as $translation ) {
	$product = wc_get_product( $translation );

	$ratings      = WC_Comments::get_rating_counts_for_product( $product );
	$review_count = WC_Comments::get_review_count_for_product( $product );

	if ( is_array( $ratings ) ) {
		foreach ( $ratings as $rating => $count ) {
			$average_ratings_sum   += $rating * $count;
			$average_ratings_count += $count;
			if ( isset( $ratings_count[ $rating ] ) ) {
				$ratings_count[ $rating ] += $count;
			} else {
				$ratings_count[ $rating ] = $count;
			}
		}
	}

	if ( $review_count ) {
		$reviews_count += $review_count;
	} else {
		update_post_meta( $translation, self::WCML_AVERAGE_RATING_KEY, null );
		update_post_meta( $translation, self::WCML_REVIEW_COUNT_KEY, null );
		update_post_meta( $translation, self::WCML_RATING_COUNT_KEY, null );
	}
}

To

foreach ( $translations as $translation ) {
	$product = wc_get_product( $translation );

	if ($product) {
		$ratings      = WC_Comments::get_rating_counts_for_product( $product );
		$review_count = WC_Comments::get_review_count_for_product( $product );

		if ( is_array( $ratings ) ) {
			foreach ( $ratings as $rating => $count ) {
				$average_ratings_sum   += $rating * $count;
				$average_ratings_count += $count;
				if ( isset( $ratings_count[ $rating ] ) ) {
					$ratings_count[ $rating ] += $count;
				} else {
					$ratings_count[ $rating ] = $count;
				}
			}
		}

		if ( $review_count ) {
			$reviews_count += $review_count;
		} else {
			update_post_meta( $translation, self::WCML_AVERAGE_RATING_KEY, null );
			update_post_meta( $translation, self::WCML_REVIEW_COUNT_KEY, null );
			update_post_meta( $translation, self::WCML_RATING_COUNT_KEY, null );
